Answer:
x = 5
y = 46
z = 88
Step-by-step explanation:
x is opposite one of the equal base angles. The other side is marked 5. Therefore x = 5
y is opposite one of the equal sides. It is an angle. It is equal to the other base angle whose measurement is given. y = 46
y + 46 + z = 180 All triangles have 180 degrees. y = 46 (above)
46 + 46 + z = 180
92 + z = 180 Subtract 92
z = 180 - 92
z = 88
