Answer:
90 degrees
Step-by-step explanation:
All trapazoids are equal to 360 degrees.
so we can make an equation 2x+x+x=360 (the other corner would also be x because its an unknown value)
to simplify, 4x=360
you divide into both sides (360/4)
you get 90

Answer:
y = 43 and x = 90
Step-by-step explanation:
We know that a triangle is 180 degrees (each side equals 180 since they are their own triangles) We will focus on the left triangle. Since x is a right angle, it is 90 degrees. Since there is a slash across the two sides of the main triangle, that means both sides are equal. This means that the bottom left angle, the one above b, is equal to 47 degrees. That means we know two angles out of 3. For the sake of simplicity, the bottom left angle, the one above b, is point z. So point z is 47, and x is 90, added they are 137. Subtract that from 180, you will get 43. 43 is y.
