How do i solve the following equation?

A Triangle has angles of
( 2 x − 10 ) ° , ( 5 x + 5 ) ° and ( 3 x ) °

Write an Equation that enables you to find the value of x
and determine the size of each angle

1 Answer

x=18.5 and the angles are 27,97.5,55.5

Explanation:

(2x-10)+(5x+5)+(3x)=180
10x-5=180
x=18.50

The angles are (2×18.5-10), (5×18.5+5), (3×18.5)" resulting into "27,97.5,55.5
