Two complimentary angles are in the ratio 4: 5 . find the angle

40° and 50°

Step-by-step explanation:

Sum the parts of the ratio, 4 + 5 = 9 parts

Complementary angle sum to 90°

Divide 90° by 9 to find the value of one part of the ratio

90 ÷ 9 = 10° ← value of 1 part, thus

4 parts = 4 × 10° = 40°

5 parts = 5 × 10° = 50°

The angles are 40° and 50°

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
