Answer:

13) 8.6

Step-by-step explanation:

To find the side length, use a trig function to solve for x.

You have the adjacent side and hypotenuse to the angle. Use the cosine function since its ratio is adjacent over hypotenuse.

This means Cos 52 = x / 14. Solve for x.

Cos 52 = x / 14

14* Cos 52 = x

8.6 = x

Need help with this question what is the correct answer?
Temka [501]

Answer:

135°

Step-by-step explanation:

Since it's a right triangle, one angle will be 90° and the other given one is 45°. The total degrees in a triangle is 180 therefore ∠CAB is 45°.

Because ∠CAB is supplementary to ∠CAD, you have to subtract 180° -- since it's a straight line -- with 45°.

This gives you 135°

Given:

The figure of a triangle DEF.

To find:

The coordinate of image of given triangle after reflection over y-axis.

Solution:

The vertices of given triangle are D(1,4), E(4,3), F(2,0).

If a figure is reflected over the y-axis, then the rule of reflection is

(x,y)\to (-x,y)

Using this rule, we get

D(1,4)\to D'(-1,4)

E(4,3)\to E'(-4,3)

F(2,0)\to F'(-2,0)

Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).
