I know that they equal 180 degrees. However I am drawinga blank on the factoring part of it

so 8x + 5 + 4 - 10 + + 2x + 10 = 180
so 5 + 10x - 175 = 0 dividethrough by 5
so + 2x - 35 = 0 now wefactor
so (x+ 7)(x - 5) = 0 so x = -7 or x = 5 if x = -7 A = -56 + 5 = - 51
but angles in a triangle do not have negative measure so theanswer is
x = 5
