Question

use the diagram to find the angle measures of the triangle. recall that the sum of the angle measures of a triangle is 180°. 5x° = (x + 5)° = x° =

Explanation:

Step1: Set up equation

$x+(x + 5)+5x=180$

Step2: Combine like - terms

$7x+5 = 180$

Step3: Solve for x

$7x=175$, so $x = 25$

Step4: Find angle measures

$x=25^{\circ}$, $x + 5=30^{\circ}$, $5x = 125^{\circ}$

Answer:

$x = 25^{\circ}$, $(x + 5)=30^{\circ}$, $5x=125^{\circ}$
