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°

<u>Perimeter of rectangular garden = 2(l + b)</u>
- 2(y + 2 + 4y - 1)
- 2y + 4 + 8y - 2
- 10y + 2.
<u>Hence, perimeter of given garden is 10y + 2</u>.
