Answer:
Part a :
x = 35
y = 110
z = 35
w = 145
Step-by-step explanation:
Part b :
It is a isosceles triangle so x and z are the same measurements.
It is s triangle so x y z all have to add to 180
in the set of numbers only 35 could work for x and z
if x and z is 35 then y has to be 110 since 35(2) is 70 and 180-70 is 110
w is 145 since z and w are supplementary
180 -35 is 145
