Find the GCF of 12 and 40​

Answer:

LN = 37

Step-by-step explanation:

Answer:

3/10

Step-by-step explanation: you multiply 3 and 1/10

Sinø=opp/hyp

Sin40=x/17. (× b.s by 17)

17Sin40=x

x=12.67

The length of perpendicular i.e., x of the right angled triangle rounded off to two decimal places is 10.92 units.

What is trigonometry ?

Trigonometry is the branch of mathematics which examines the relationship between triangle sides and angles as well as the relevant functions of any angle.

A right angled triangle is given which has an angle of measure 40° and a side of 17 units. We know that to find out the perpendicular or any other side in a right angled triangle we use trigonometry.

Using the formula for sin θ which states that :

sin θ = Perpendicular / hypotenuse

As , the perpendicular is x , the value of which we have to calculate.

sin 40° = x / 17

x = 17 × sin 40°

x = 17 × 0.6428

x = 10.9276

If we round off it to two decimal places we get :

x = 10.92 units

Therefore , the length of perpendicular i.e., x of the right angled triangle rounded off to two decimal places is 10.92 units.

Steps to solve:

8 / -2 * 42 + 9

~Divide

-4 * 42 + 9

~Multiply

-168 + 9

~Add

177

Best of Luck!

The simplified expression is equivalent to -159.

Given is an expression 8 ÷ -2 · 42 + 9, we need to simplify it,

To evaluate the expression 8 ÷ -2 · 42 + 9, we need to follow the order of operations, which is typically remembered using the acronym PEMDAS.

In this case, we should first perform the multiplication and division, and then the addition.

Starting with the multiplication and division:

8 ÷ -2 = -4

-4 · 42 = -168

Now we can add the result to 9:

-168 + 9 = -159

Therefore, the evaluation of 8 ÷ -2 · 42 + 9 is -159.

Answer:

- 4.2 degrees

Step-by-step explanation:

If the drop was from temp 0 at 8 pm to temp -16.8 at midnight (4 hours later)

then,the drop is given by the rate: -16.8/4 = - 4.2 degrees per hour

Therefore, at 9 pm the temperature was:

0 degrees - 4.2 degrees = - 4.2 degrees

Answer:

Question 21

Question 22

Question 23

Step-by-step explanation:

When the question says a line bisects an angle which means that this line is cut exactly at the centre of an angle so both angles will be the same :

Question 21,

[tex]∠PQR = ∠SQR[/tex]

[tex]∠PQS = 22°[/tex]

[tex]∠PQR = ∠PQS + ∠SQR[/tex]

[tex]∠PQR = 22 + 22 = 44°[/tex]

Question 22,

[tex]∠ABD = 94°[/tex]

[tex]∠ABC = ∠CBD = 94 \div 2 = 47°[/tex]

Question 23,

[tex]∠ABD = ∠DBC[/tex]

[tex]x + 15 = 4x - 45[/tex]

[tex]4x - x = 15 + 45[/tex]

[tex]3x = 60[/tex]

[tex]x = 60 ÷ 3 = 20°[/tex]

[tex]∠ABD = 20 + 15 = 35°[/tex]

[tex]∠DBC = 4(20) - 45 = 35°[/tex]

[tex]∠ABC = ∠ABD + ∠DBC = 35 + 35 = 70°[/tex]

Answer: It is being dilated by a scale factor of 1/3.

Step-by-step explanation:

The pre-image has the coordinates (0,0) (6,0) (6,-3) and (0,-3) and a transformation has been applied to it to get the coordinates of the image to be (0,0) (2,0) (2,-1) ( 0,-1)

Looking at the coordinates we can see that to get from 6 to 2 you will have to multiply by  1/3 and to  get from -3 to -1 you will have to multiply by 1/3.

This means that pre-image was dilated  by a scale factor of 1/3.

Answer:

Short answer: the pre-image was dilated  by a scale factor of 1/3.
