Question

angle A and Angle B are complementary angles if angle A is equals to 7 degree + 4 x and Angle B is equals to X + 23 degree find x

Answer 1

Here, it is given that

Angle A = 7° + 4x
Angle B = 23° + x

We know that two angles are said to be complementary if the sum of both angles = 90°

Then,According to question,

$7 + 4x + 23 + x = 90$
$5x + 30 = 90$
$5x = 90 - 30$
$5x = 60$
$x = \frac{60}{5}$
$x = 12$
That is your answer.

Answer 2

x=12 hope this answers help you
