Question

Two complementary angies are (x 5) and (3x - 7). Find the value of x.
​

Answer 1

Answer:

Since I'm not sure whether it is 5x or x+5, I'm gonna do both, please check with the question again

Case 1

5x + 3x - 7 = 90

8x = 90 + 7

97/8 = x

x= 12.125

Case 2

x + 5 + 3x -7 = 90

x + 3x -2 = 90

4x = 90 +2

x= 92/4 = 23

Answer 2

➡️Angles whose sum is 90° are called complementary angles.

☯️Two complementary angles are (x +5) and (3x - 7). Find the value of x.

➡️First complementary angle = (x+5)

second complementary angle = (3x-7)

A.T.Q

(x+5) + (3x -7) = 90°

x+5 + 3x -7 = 90°

4x-2= 90°

4x = 90°+2

4x= 92

x= 92/4

x= 23

⚛️So, the value of x is 23°
