Answer:
y>9/16
Step-by-step explanation:
Step-by-step explanation:
1) y=60°(alternate angle
2) x+60°=180°(exterior angles)
x=180°-60°
x=120°
Answer:
C. 115°,65°
Step-by-step explanation:
Make the equation for ∠A equal the equation for ∠C: 100+5x=106+3x. You will find x=3. So you plug that into the equations for ∠A and ∠C. And you know that ∠A and ∠C both equal 115°. You repeat these steps for angles B and D and they equal 65°. Ya welcome.
Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A pentagon has n = 5, thus
sum = 180° × 3 = 540°
