the measure of a supplement of an angle exceeds 10 times the measure of its complement by 9. Find the measure of the angle
Answer:
81°
Step-by-step explanation:
Let the angle be x. Then,
complementary angle = 90 - xsupplementary angle = 180 - xAccording to question,
=> 180 - x - 10(90 - x) = 9
=> 180 - x - 900 + 10x = 9
=> 9x - 720 = 9
=> 9x = 729
=> x = 81
The measure of the angle is 81° (ans)
Answer:
81°
Step-by-step explanation:
Definitions
Complementary angles: Two angles whose measures sum to 90°.
Supplementary angles: Two angles whose measures sum to 180°.
Define the unknown angle
Let x be the unknown angle.Therefore:
Complement of x = 90° - x°Supplement of x = 180° - x°If the measure of the supplement exceeds 10 times the measure of its complement by 9:
⇒ supplement = 10 × complement + 9
⇒ (180 - x) = 10(90 - x) + 9
⇒ 180 - x = 900 - 10x + 9
⇒ 180 - x = 909 - 10x
⇒ 180 - x + 10x = 909 - 10x + 10x
⇒ 180 + 9x = 909
⇒ 180 + 9x - 180 = 909 - 180
⇒ 9x = 729
⇒ 9x ÷ 9 = 729 ÷ 9
⇒ x = 81
Therefore, the measure of the angle is 81°.

The first side of a triangle is 3 m shorter than the second side. The third side is 4 times as long as the first side. The perimeter is 27 m. Find the length of the 1st side.
Answer: the length of the 1st side is 4 m
Step-by-step explanation:
P=a+b+c
b=a+3
c=4a
Hence,
27=a+(a+3)+4a
27=a+a+3+4a
27=6a+3
27-3=6a+3-3
24=6a
Divide both parts of the equation by 6:
4=a
Thus,
a=4 m
a. What is the solution of the system? Use elimination.
x-2y+3 z = 12
2x-y-2z = 5
2x+2 y-z = 4
By elimination, the solution of the system of equations, x - 2y + 3z = 12, 2x - y - 2z = 5 and 2x + 2y - z = 4, is (4 , -1 , 2).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Given:
x - 2y + 3z = 12 (equation 1)
2x - y - 2z = 5 (equation 2)
2x + 2y - z = 4 (equation 3)
Using the elimination method, given the equations in x, y, and z, a variable should be eliminated by adding/subtracting the equations.
Adding equations 1 and 3 will eliminate the variable y.
x - 2y + 3z = 12 (equation 1)
2x + 2y - z = 4 (equation 3)
3x + 2z = 16 (equation 4)
Multiply equation 2 by 2 and add with equation 3.
2x - y - 2z = 5 (equation 2)
⇒ 4x - 2y - 4z = 10
+ 2x + 2y - z = 4 (equation 3)
6x - 5z = 14 (equation 5)
Multiply equation 4 by 2 and subtract with equation 5.
3x + 2z = 16 (equation 4)
⇒ 6x + 4z = 32
- (6x - 5z = 14) (equation 5)
9z = 18
z = 2
Substitute the value of z to either equation 4 or 5 and solve for x.
3x + 2z = 16 (equation 4)
3x + 2(2) = 16
3x = 16 - 4
3x = 12
x = 4
Finally, substitute the value of x and z to any of the first three equations, and solve for y.
x - 2y + 3z = 12 (equation 1)
4 - 2y + 3(2) = 12
-2y = 12 - 4 - 6
-2y = 2
y = -1
Hence, the solution of the system of equations is (4 , -1 , 2).

Solve for x:
1/3 |x-3|+ 4 = 10
Answer:
x=-15 and x=-15
Step-by-step explanation:
We try to move everything from the left to the right starting with the number that is further away from x, so 4. We subtract it from both sides.
1/3|x-3|+4-4=10-4
1/3|x-3|=6
Next, we have the fraction so basically, 1 is being divided by 3 so we are going to multiply both sides by three.
1/3|x-3|×3=6×3
|x-3|=18
We get rid of the absolute value signs to get
x-3=18
But we are not sure if 18 is negative so we put it like this.
x-3=-18
x-3=18
Then we add 3 from both sides.
x-3+3=-18+3
x-3+3=18+3
Which equals:
x=-15
x=21

What is an arithmetic sequence?A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
Now,
Given: 6, 3, 0, -3, ....; it is a decreasing AP.
Here, a = 6 (initial term) and d = -3 (common difference)
Thus, in the formula: [tex]a_n[/tex] = a + (n - 1) d, substituting these values:
=> [tex]a_n[/tex] = 6 + (n - 1)(-3)
For ninth term, n = 9
Thus, [tex]a_n[/tex] = [tex]a_9[/tex] = 6 + (9 - 1)(-3)
=> [tex]a_9[/tex] = 6 + (8)(-3)
=> [tex]a_9[/tex] = 6 -24
=> [tex]a_9[/tex] = -18
Similarly, for the tenth term, n = 10
Thus, [tex]a_n=a_{10}[/tex] = 6 + (10 -1) (-3)
=> [tex]a_{10}[/tex] = 6 + (9) (-3)

What is the AP arithmetic progression sequence?The difference between two numerical orders is a constant value in Arithmetic Progression (AP). Another name for it is Arithmetic Sequence.
We'd emerge across a few fundamental words in AP that have been labeled as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)The AP can also be described in terms of common differences, as shown below.
The procedure for appraising an AP's n-th term is as follows: an = a + (n − 1) × dThe following is the arithmetic progression sum: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, the given sequence is; 100,117,134,151,168, ...........
The series comprises of five given terms.
Let the initial term be 'a₁' = 100.
The second term be 'a₂' = 117.
The third term be 'a₃' = 134.
And, the fourth term is 'a₄' = 151.
The AP must have the equal common difference. So,
d = a₃ - a₂
Substitute the values.
d = 134 - 117
d = 17
Thus, the computed common difference is 17.
or d = a₄ - a₃ (Substitute the values)
d = 151 - 134
d = 17
Since, a₃ - a₂ = a₄ - a₃
Thus, we can get to know that the given sequence is in AP.
Now, the 6th term is estimated as; a₆ = a₅ + d = 168 + 17
a₆ = 185
Similarly, the 7th term will be; a₇ = a₆ + d = 185 + 17
a₇ = 202
And, the 8th term will be calculated as; a₈ = a₈ + d = 202 + 17
a₈ = 219.
Therefore, it can be said that the given sequence is in AP next three terms be 185, 202, 219.
