Question

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

Answer 1

Answer:

x=32

Step-by-step 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

Answer 2

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