Angle A and angle B are complementary. The measure of angle A is five less than four times the measure of angle B. Find the measure of the smaller angle

Step-by-step explanation:

Let angle B = x

∠ A = 4x -5

Angle A and angle B are complementary.

∠ A + ∠ B = 90

4x - 5 + x = 90

5x - 5 = 90

5x = 90+5

5x = 95

x = 95/5

x = 19

The measure of smaller angle = 19

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
