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°
C90,2) - Not a right triangle
C(3,-1) - is a right triangle ( its slope is a negative inverse )
C(0,4) - is a right triangle ( its slope is a negative inverse )
Divide the figure into two rectangles:
12*3 (top) + 6*6 (bottom) = 72 yd^2
