The missing angles of triangles are - 30°, 50°, 40°.

According to the triangle's "angle sum property," a triangle's angles add up to 180 degrees. Three sides and three angles, one at each vertex, make up a triangle. The sum of the internal angles of a triangle is always 180o, regardless of whether it is acute, obtuse, or right.

There are 5 triangles in the given diagram,

We will see them anti - clock wise.

All the triangles are right - angled triangle.

The measures of 1 triangle are -

90°, Let the other 2 angles be x,y

The measures of the 2nd triangle are -

Given,

60°, 90°

Using angle sum property,

The measure of third angle = 180°

= 60 + 90 + third angle = 180

third angle = 180 - 150

= 30.

The measures of 3rd triangle are -

Given,

40°, 90°

Using angle sum property,

The measure of third angle = 180°

= 40 + 90 + third angle = 180

third angle = 180 - 130

= 50.

The measures of 4th triangle are -

50°, 90°

Using angle sum property,

The measure of third angle = 180°

= 50 + 90 + third angle = 180

third angle = 180 - 140

= 40.

True, The sequence an = 8, 13, 18, 23, ...is the same as the sequence a₁ = 8,

an = an-1 +5.

An arithmetic sequence is a set of integers which follow a specific pattern. It is an arithmetic sequence if you pick any number in the sequence and subtract it from the preceding one, and the result is always the same or constant.

The common difference, indicated by the letter d, is the constant difference between all pairs of consecutive or succeeding numbers in a sequence. To transition from one phrase to another, we use the common difference. How? To get to the following term, take the current term and add the common difference, and so on. That is how the sequence's terms are formed.

The first equation is as follows: a(sub n) = 8, 13, 18, 23.

The second equation is: a(sub 1)=8; a(sub n)= a(sub n-1)+5

To obtain the second term, enter two into the equation for n 8+5=13. To find the third, enter the second term, 13, into the equation for n 13+5=18.

If the total charge on 8 particles is -56 units and all the particles have the same charge, then the charge on each particle is equal to -7 units.

The charge on each particle can be determined by division.

Division is a part of the basic operations of arithmetic which are four in number, the rest being addition, subtraction, and multiplication. It can be considered the opposite of multiplication and involves separating into equal parts or groups.

The change on each particle can be calculated by dividing the total charge units by the total number of particles. Hence,

charge on each particle = total charge units ÷ total number of particles

charge on each particle = -56 / 8

charge on each particle = -7

Therefore, the charge on each particle is equal to -7 units if all the particles have the same charge.

Any of the basic arithmetic operations—addition, subtraction, multiplication, division, raising to the power of a whole number, and taking roots (fractional power)—is considered an algebraic operation. These procedures could be applied to numerical data, in which case they are frequently referred to as arithmetic operations. Similar operations can be carried out on variables, algebraic expressions, and, more generally, on components of algebraic structures like groups and fields. Another way to describe an algebraic operation is as a function from the Cartesian power of a set to the same set.

It's difficult to determine the solution because we don't know how much money she had in her bank account before making 4 withdrawals, thus a like and rating would be really appreciated. We know she took out $40 four times, which is $160. She also used her card to make a $156 purchase, so when we sum the two amounts, we get $316. She then placed a check for $375 into the bank account, therefore we must deduct $316 from that sum to get at $59; but, since we deducted, Given that we end up with $59 rather than the money we wasted at the beginning, the fact that the price is higher than $316 indicates that there has been an increase.

The blanks in the  question has same value and it is equal to 9

Given data

6x​ + ____ =7x-​____ ​, solution is 18

let the missing number be in the left hand side of the equation be equal to  the missing number at the right hand side of the equation and both be represented by y.

if the solution is x which is 18 we substitute for y as follows

6x + y = 7x - y

y + y = 7x + 6x

plugging in the values of x

y + y = 7 * 18 - 6 * 18

2y = 126 - 108

2y = 18

y = 9

testing y = 9 in both equations

6x + y = 6 * 18 + 9 = 108 + 9 = 117

7x + y = 7 * 18 - 9 = 126 - 9 = 117

Based on the total budget of Mr. Bell for the incentive and the cost of a pizza box, the equation that matches the word problem is 60 ≥ 9.25x

The amount that Mr. Bell will spend at the most is the budget for the incentive of $60.

He will not spend more than this amount but will spend a maximum of it. This amount of $60 is therefore equal to or greater than the cost of the pizzas:

60 ≥ cost of the pizza

The cost of the pizza is:

= Cost per pizza box x number of boxes

Step-by-step explanation: We can identify the number of significant digits by counting all the values starting from the 1st non-zero digit located on the left. For example, 12.45 has four significant digits.

The total fencing material needed for the triangular plot is 537.03 feet.

A trigonometric law: the square of a plane triangle's side equals the sum of the squares of a remaining sides minus double the the product of such sides as well as the cosine of a angle between them.

If the triangle ABC is having the sides a, b and c.

Then, the formula for law of cosine is;

c² = a² + b² - 2abcosC

Now, as per the given question;

The first step is to compute the length of the fence's third side. The following formula can be used to calculate the length of a third side:

c² = a² + b² - 2abcosC

Where a,b and c are the three sides and C is the angle forming between sides a and b.

The sides are a = 160 feet, b = 160 feet.

The angle between the sides a and b is 85 degrees.

Now, estimate for c by substituting all the value in the formula.

c² = 160² + 160² - (2 x 160 x 160)cos85

c² = 51,200 - 51200 x0.087

c = √47104

c = 217.03 feet

Now, the total length of the perimeter = 160 + 160 + 217.03

                                                               = 537.03 feet                

Therefore, the total length of the perimeter of the fencing material is found to be 537.03 feet.
