Answer:
x= 113
y= 67
z= 49
Step-by-step explanation:
a triangle equals to 180° so lets start with the triangle that has two given degrees
28 + 39 + x = 180 solve
x = 113
no we can find y by using x + y = 180 since it's a straight line
we know the value of x so 113 + y = 180. solve.
y= 67
now do the same thing we did from the start since we have two given degrees on the other triangle.
67 + 64 + z = 180
z= 49
