Find the values of x, y, and z. the diagram is not to scale.
a. x = 86, y = 94, z = 75
b. x = 86, y = 75, z = 94
c. x = 75, y = 94, z = 86
d. x = 75, y = 86, z = 94

All the angles must add to 180degrees in a triangle.

180 = 59 + 35 + x
180 = 94 + x
86 = x

Supplementary angles x and z add to 180
180 = x + z
180 = 86 + z
94 = z

Now the last triangle is with angles 11, z, and y
they must add to 180 so...
180 = 11 + z + y
180 = 11 + 94 + y
180 = 105 + y
75 = y

The answer is B.)

Hope this helps!

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats
