Question

How can I solve this?

Answer 1

Answer:

y is 70° and x is 40 °

Step-by-step explanation:

the triangle has two equal sides as shown on the diagram...so the next angle to 110° which is 70° is equal to y....then by calculation y + x should give us 110° so if y is 70 then x is 40.

Answer 2

Answer:

y = 70

x = 40

Step-by-step explanation:

The interior angle connected to 110o is the supplement of the 110o angle.

180 - 110 = 70o

The triangle is marked as having 2 equal sides which means that there must be 2 equal angles opposite these 2 sides. Therefore y is also 70o

All triangles have 180o

Therefore x + y + y = 180

We know the ys = 70 each. Substitute into the equation above

x + 70 + 70 = 180                  Combine  

x + 140 = 180                         Subtract 140 from both sides.

x = 180 -  140

x = 40
