How do I do this problem?

4 0

To solve the problem, we can use the angle sum of triangle,where the addition of all triangles would be equal to 180°.

In this case, 90° is already given, hence we can use the rest angles with unknown to set up equaiton:

90° + 2x + 3x = 180°

2x + 3x = 180°- 90°

5x = 90°

x = 90°/5

x = 18°

Therefore, x= 18°.

Hope it helps!

xxTIMURxx [149]

Answer:

ET = 80/A^2

Step-by-step explanation:

First, isolate the variables that you need, which is E and T, using the two equations you were given.

EA = 8

E = 8/A (divide A on both sides to isolate E)

AT = 10

T = 10/A (divide A on both sides to isolate T)

Now, substitute.
