the two figures below are congruent. find the measure of the angle that isn't labeled on either figure.
1 answer:
Hello!
Since the shapes are congruent the angles are the same
The angles are 133, 41, 86
The angles in a quadrilateral add to 360
We subtract the numbers from 360 to get the measure of the unknown angle
360 - 133 - 41 - 86 = 100
The answer is 100°
Hope this helps!

long way
12 x 11 x 10 x 9 x 8 x 7 x6 x5 x4 x3x2/ 10x9x8x7x6x5x4x3x2x
but you can shorten that by crossing out identical numbers so you get 12 x 11
12 x 11 = 132 combinations
This is how you would solve the question.
