In the triangle below, suppose that m angle L=(5x-3)m angle M=(4x-7)^ , and m angle N=x Find the degree measure of each angle in the triangle .
Please I need this done in 15 minutes !!!!!
1 answer:
Because all angles adds up to 180 we are going to add the equations and equal it to 180. 5x - 3 + 4x - 7 + x = 180 5x + 4x + x - 3 - 7 = 180 10x - 10 = 180 10x = 180 + 10 10x / 10 = 190/10 x = 19 degrees 5x - 3 5(19) - 3 = 92 degrees 4x - 7 4(19) - 7 = 69 degrees angle L = 92 degrees angle M = 69 degrees angle N = 19 degrees
