Question

Find x, y, and z. Please help :)

Answer 1

Answer:

x = 55°, y = 70° and z = 125°

Step-by-step explanation:

Step 1 - Calculate ∠x:

As all angles on a line add up to 180°

125 + x = 180

x = 180 - 125

x = 55

Step 2 - Calculate ∠y:

As the triangle is an isosceles triangle, as evident by the two sides of equal length:

180 = y + 55 + 55

180 = y + 110

y = 180 - 110

y = 70

Step 3 - Calculate z:

180 - 55 = z

z = 125

Meaning that x = 55°, y = 70° and z = 125°

Hope this helps!
