What Is The Measure Of Angle C class=

Answer :

Answer:

83.5

Step-by-step explanation:

x + 4x + 5x -13 =180  The sum of the interior angles of a triangle is 180

10x - 13 = 180 Combine like terms

10x = 193  Add 13 to both sides

x = 19.3 degrees.

Substitute 19.3 for x in the expression for C

5x -13

5(19.3) -13

83.5
