angle a and angle b are both complementary angles. the measure of angle b is (4x) and the measure of angle a is 50. whats the value of x show work. answer asap please

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

the answer to 1/4x+5/3x-4=2-1/12x is x=3

hope this if needed hmu

in my opinion , its hazel
