Question

In triangle xyz, m∠y = 45.43° and m∠z = 38.7°. determine the measure of the exterior angle to ∠x. 44.57° 51.3° 75.75° 84.13°

Answer 1

Explanation:

USE THE EXTERIOR ANGLE THEROME!
FIRST

THE FOMULA

a+b=c

y+z=x

now we have to add y and z

45.43 + 38.7

which gives us 84.13!

Answer 2

`84.13^(\circ)`

Explanation:

By the exterior angle theorem, the answer is
`m\angle y+m\angle z=84.13^(\circ)`.
