Question

The degree measures of the angles of a triangle are represented by x, 3x and 5x -54.
Find the value of x.

Answer 1

Answer:

x = 26

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + 3x + 5x - 54 = 180 , that is

9x - 54 = 180 ( add 54 to both sides )

9x = 234 ( divide both sides by 9 )

x = 26
