Question

What is the value of x then find the messures of Angles M and N​

Answer 1

step 1 solve for x step 2 after getting the value of x ,substitute and get the value of angles

Answer 2

x=32

Explanation:

sum of interior angles of a triangle = 180

add up all angles and equate to 180

(4x-13)+(x+18)+15=180

5x=160

x=160/5=32

x+18 = 32+18 = 50

4x-13 = 4x32-13 = 128-13 = 115

add up all to check whether ans = 180; 15+50+115=180
