The value of x from the given figure is 11
<h3>Complementary angles</h3>
The sum of two complementary angles is 90 degrees.
The angles shown in the diagram are complementary such that;
20 + 5x + 15 = 90
5x + 35 = 90
5x = 90- 35
5x = 55
x = 55/5
x = 11
Hence the value of x from the given figure is 11

Answer:
Step-by-step explanation:
Hello,
The circumference of the cake is 25(1/7), but we don't know the area of the cake.
Assuming the cake has a shape of a circle,
Circumference of a circle = 2πr
Where r = radius of the circle.
Area of a circle = πr²
But π = 22 / 7
We have to first find the value of r.
2πr = 25(1/7)
2×(22/7)×r = 25(1/7)
(44/7)r = 176 / 7
(44 × 7)r = 176 × 7
44r = 176
r = 176 / 44
r = 4 inches
Area of the circle = πr²
A = (22 / 7) × 4²
A = 22 / 7 × 16
A = 352 / 16
A = 22 (inches)²
The area of the cake is 22in²
