because were dealing with a right angle, both the angle of m1 and m2 two together should equal 90 degrees! therefore set up the equation as 8x + x - 9 = 90
we can simplify it to 9x = 99 (adding the x’s and adding the 9 to both sides)
so x = 11
great! now lets solve for the angles by plugging it in.
8(11) = 88 (m1)
(11)-9 = 2 (m2)
hope this helps!
