Question

If angles A and B are complimentary angles. What are angles A and B equal to if angle A is 4x + 10 and angle B is x.

Answer 1

Answer:

B = 16°

A = 74°

Step-by-step explanation:

A + B = 90°

4x + 10 + x = 90°

5x + 10 = 90°

5x = 80°

x = 80/5

x = 16°

=================================================================

B = 16°

A = 90° - 16° = 74°

Answer 2

Answer: Angle A is equal to 74 degrees, and Angle B is equal to 16 degrees.

Step-by-step explanation:

First we need to understand that ∠A +∠B is equal to 90 degrees.

Now form it into an equation: (4x+10)+(x)=90

Now, solve the equation-

(4x+10)+(x)=90

(4x+x)+10=90

5x+10=90

5x=90-10

5x=80

x=16

Now substitute this value into both of the equations.

4x+10

4(16)+10

64+10

=74

x

=16

Therefore, Angle A is 74 degrees

                  Angle B is 16 degrees

Hope it helped!
