Question

Angle A and angle B are complementary angles. The measure of angle B is 65*. What is the value of x?

Answer 1

x=25

Explanation:

Complementary angles:

Complementary angles are 2 angles that when added together, equals 90 degrees, or a right angle.

We already know that they are complementary, but we have to find the measure of 1 angle, given the other angle measure.

We can write an equation like this:
90=65+x

subtract 65 from both sides

25=x

So, x=25.

Hope this helps! :)

Answer 2

x=25°

Explanation:

If angle A and angle B are complementary angles, it means that the sum of their measures is equal to 90 degrees.

Let's denote the measure of angle A as x. Since angle B is given as 65 degrees, we can write the following equation:

x + 65 = 90

To solve for x, we can subtract 65 from both sides of the equation:

x = 90 - 65

x = 25

Therefore, the value of x is 25.
