Question

geometry : A trapezoid has angles that measures 3x°,3x°,x° and x°, what is the value of x?​

Answer 1

Answer:

Step-by-step explanation:

Any 4 sided figure closed and convex, has interior angles that add to 360 degrees

x + x + 3x + 3x = 360   Combine all like terms on the left.

8x = 360                       Divide both sides by 8

8x/8 = 360/8

x = 45

The value of x is 45.
