Question

one angle of a triangle measures 12 degrees. the second angle's measurement is five times the third.what is the measure of the third angle

Answer 1

let x = measure of third angle


so the second angle is 5x because "the second angle's measurement is five times the third"


The first angle is 12


-------------------------------------------------------

All three angles in the triangle must add to 180 degrees, so


12 + 5x + x = 180


solve for x to get your answer

Answer 2

is 28 correct

Answer 3

good, x = 28

Answer 4

so the third angle is 28 degrees
