Answer:
x = 40°
Angle A: 118°
Angle B: 120°
Angle C: 62°
Angle D: 60°
Step-by-step explanation:
When a quadrilateral is inscribed inside a circle, opposite angles add up to 180.
(x + 20) + 3x = 180
4x + 20 = 180
4x = 160
x = 40°
Angle A: 2(40) + 38 = 118°
Angle B: 3(40) = 120°
Angle C: 180 - 118 = 62°
Angle D: 40 + 20 = 60°
They are equal because
1 yd=3ft
25 yds= x feet
x= 25*3
feet=75
let's recall that an equilateral triangle has all interior angles of 60°.
Check the picture below.
so as you can see, 2√3 = x = r, namely the radius of the circle.
