6. The measures of the three angles of a triangle
are (3x), (x - 15)° and (2x + 15). What is the
measure of the angle with the greatest measure?

Respuesta :

90

3x+x-15+2x+15=180
6x=180
Divide each side by 6
X= 30

Now go back to each angle and substitute 30 for x

(3 x 30)= 90
(30-15)= 15
(2(30)+15)=75
