The complement of an acute angle A in degrees is 90 - A. So if the complement is 25 degrees, the angle would be 90 - 25 = 65 degrees.
We can find the area of the big triangle, and subtract it from the small 4 x 2 triangle.

To find the perimeter:
a² + b² = c²
9 + 64 = c²
73 = c²
√73 = c
√73 + 3 + 8 + 2 + 4
√73 + 17

The absolute value of a number is its distance from 0.
The area of circle is 12312 yd^2
Step-by-step explanation:
Given
Area of 20° sector = 684 yd^3
First of all, we have to find the number of total 20° sectors in the whole circle
so,
Number of sectors = 360/20 = 18 sectors
The total number of sectors is 18
So,
The area of 18 sectors will be:
18*684 = 12312 yd^2
The area of circle is 12312 yd^2
Keywords: Circle, sectors
