Question

What is the value of s?

Answer 1

108 + 39 + s = 180
147 + s = 180
147 - 147 + s = 180 - 147
s = 33

Answer 2

Answer:

The answer to your question is 33°

Step-by-step explanation:

Data

∠1 = 39°

∠2 = 108°

∠3 = ?

Process

To solve this problem, remember that the sum of the internal angles in a triangle equals 180°.

Then,

              ∠1 + ∠2 + ∠3 = 180°

-Substitution

             39° + 108° + ∠3 = 180°

-Solve for ∠3

              ∠3 = 180 - 39 - 108

-Simplification

              ∠3 = 180° - 147°

-Result

•               ∠3 = 33°
