Question

Find the length of each missing side and each missing angle in the isosceles triangles below

Answer 1

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
