One of two complementary angles is 4 degrees more than the other. find the angles. (recall that complementary angles are angles whose sum is 90 degrees.)

which of the following equations can not be used to solve the problem if x represents one of the angles?

2x - 4 = 90
2x + 4 = 90
x + 4 = 90

Answer : The equation can not be used to solve the problem is, x + 4 = 90

Step-by-step explanation :

As we are given that one of two complementary angles is 4 degrees more than the other. That means,

There are two situations.

(1) Let the smaller angle be, 'x'

and the bigger angle will be, (x+4)

As, complementary angles are angles whose sum is 90 degrees. That means,

Smaller angle + Bigger angle = 90°

Thus, the equation will be:

x + (x+4) = 90°

2x + 4 = 90°

(2) Let the bigger angle be, 'x'

and the smaller angle will be, (x-4)

As, complementary angles are angles whose sum is 90 degrees. That means,

Smaller angle + Bigger angle = 90°

Thus, the equation will be:

(x-4) + x = 90°

2x - 4 = 90°

Thus, the equation can not be used to solve the problem is, x + 4 = 90
