Answer:
<h2>137°</h2>
Step-by-step explanation:
The pentagon RSTYZ is a regular polygon. Therefore all angles are congruent.
If m∠RST = 108°, then m∠STY = 108°.
We have the equation:
m∠UTY + m∠STY + m∠STU = 360°.
Substitute m∠STY = 108° and m∠UTY = 115°.
115° + 108° + m∠STU = 360°
223° + m∠STU = 360° <em>subtract 223° from both sides</em>
m∠STU = 137°
48 because 6 multiply by 8 equals 48
