In the triangle one angle is five more than a number. the second number is twice the measure of the first angle. the third angle measures 99°. find the measure of each angle.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

i suppose it should be (y=2x-5)
