If ∠H and ∠J are complementary, it means that the sum of their measures is 90°.

Given that the measure of ∠H is 45°, we can calculate the measure of ∠J by subtracting the measure of ∠H from 90°:

90° - 45° = 45°

Therefore, the measure of ∠J is 45°.
Angles j and k are supplementary angles. What is m∠j if m∠k = 117°?

m∠j = Response area
If angles J and K are supplementary, it means that the sum of their measures is 180°.

Given that m∠K = 117°, we can calculate m∠J by subtracting the measure of ∠K from 180°:

180° - 117° = 63°

Therefore, m∠J = 63°.
What is an equation for these two supplementary angles?

(2x + 3) + (x - 6) = Response area
An equation for the two supplementary angles can be written as:

(2x + 3) + (x - 6) = 180

To find the measure of angle x, we need to set up an equation based on the fact that the two angles are supplementary.

Let's assume that one angle is x°. Then the other angle, being supplementary, would be 180° - x°.

Setting up the equation:

x° + (180° - x°) = 180°

Simplifying the equation:

x° + 180° - x° = 180°

180° cancels out on both sides of the equation:

0 = 0

Since 0 = 0 is always true, it means that any value of x would satisfy this equation. Therefore, the measure of angle x can be any value.
