Answer:

x = 20°, y = 70° see image

Explanation:

Use the bottom, lower, short wide triangle first. It has marks on it to show that two of the sides are the same length. That means that the opposite angles are the same. One is marked x, so the other is also x. There is a 40° angle given, along the same line right next to it has to be 140°. We'll use that one.

Also, the angles in a triangle add up to 180°.

x° + x° + 140° = 180°

See image for calculations.

Then we use the whole entire triangle. It has a 90° angle and the 20° (for x, that we just found) and y. We'll use that to find y.

90° + y + 20° = 180°

See image for calculations.
