Question

The measures of the angles of a triangle are shown in the figure below. Solve for x.

(4x-3)°
(4x+10)°
(6x-9)°

Answer 1

so all angles have to equal 180°, so set them all equal to 180. For example, (4x-3)(4x+10)(6x-9) = 180. then solve it like you would normally! and whatever x is, replace it into the problems. For example if x is 1 you would plug it back in, 4(1)-3
