Question

What are the values of s and t?

Answer 1

t = 36°

s = 108°

Explanation:

FE and DE are congruent. This means that triangle ΔDEF is isosceles.

Base angles (∠EFD and ∠EDF) in isosceles triangles are congurent.

∠EFD is 36°. This means that ∠t is also 36°

The measure of all the angles in a triangle is 180°

`36+36+x=180\\72+x=180\\x=108`

∠s = 108°

Answer 2

s=144

t=36

Explanation:

you minus 180 from 36 and you get 144 for s

then you minus 180 from 144 to get t
