Answer:
18°
Step-by-step explanation:
1. ∠A and ∠B are complementary angles, so they add up to 90°.
- This means that 2x - 4 + 5x + 17 = 90
2. To find the measure of ∠A, we first have to solve for x.
3. (Solving)
Step 1: Simplify both sides of the equation.
Step 2: Subtract 13 from both sides.
Step 3: Divide both sides by 7.
4. Now that we know x = 11, let's plug that value into (2x - 4) to find the measure of Angle A.
Therefore, the measure of ∠A = 18°.

Step-by-step explanation:
x is the number.
(x + 5) - 2x : the sum of the number and 5 decreased by twice the number.
or simplified without the brackets
x + 5 - 2x = 5 - x
it is not clear if you need the general expression showing both conditions (the first up there), or the then simplified result
5 - x
