Question

I need help with this please ASAP!!!!

Answer 1

Answer: Part 1, 360

Part 2, (x + 300 = 360)

Part 3, x = 60°

Step-by-step explanation: First things first, the figure given in the question is a quadrilateral (four sided figure). The sum of the interior angles of a quadrilateral equals 360°.

So, if three angles have been given and one angle is yet unknown, to calculate the unknown angle we simply write out the expression

Sum of interior angles = 360

x + 91 + 120 + 89 = 360

x + 300 = 360

Subtract 300 from both sides of the equation

x = 60.

Therefore, the fourth angle x measures 60°

Answer 2

X=60 you need to add it up to 360 everything on it adds to 300 so that makes x 60.
