The measure of an angle is 6 less than 5 times its complement. what is the measure of its complement

ra1l [238]

Measure of angle is 6 less than 5 times its complement,
Equation is:
A= 5 x (90 - A) - 6
Solve for A.
A=5(90-A)-6
A=450-5A-6
Add 5A to both sides
6A=444
A=74°
Now the complementary angle=90°-74° =16°

Math's the devil but help plz

erma4kov [3.2K]

Using the apothem, a, and the perimeter, p, the area, A, of a regular polygon is

$A = \dfrac{pa}{2}$

You need to calculate the area of the octagon and subtract the area of the square.
The perimeter is 8 times the side.

$A = \dfrac{pa}{2} - s^2$

$A = \dfrac{8 \times 13 \times 15.69}{2} - 13^2$

$A = 815.88 - 169$

$A = 646.88$
