Two angles are supplementary. The measure of angle 1 is equal to 12x+4 and the measure of angle 2 is equal to 4(2x+5).what is the measure of angle 2?

82.4

Step-by-step explanation:

12x+4+8x+20=180

20x+24=180

-24 -24

20x= 156

x= 7.8

Angle 2

4(2*7.8 +5)

4(15.6+5)

4(20.6)

82.4

step-by-step explanation:

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
