Help! Find x, y, z <br> Worth 20 points
GenaCL600 [577]

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
