Answer:

116

Step-by-step explanation:

The sum of angles in a quadrilateral is 360°. The figure here is symmetrical about the line NQ, so ∠P = ∠M = x°. Using these facts, we can write ...

∠M +∠N +∠P +∠Q = 360°

x° +28° +x° +100° = 360° . . . . fill in the angle values

2x = 232 . . . . . . . . . . . . . . . . . divide by °, subtract 128

x = 116 . . . . divide by 2

Solve for x no work needed

wariber [46]

Answer:

$\huge\boxed{82 \textdegree}$

Step-by-step explanation:

We know that all angles in a triangle will add up to 180°. Since we know the measure of all 3 angles, we can create this equation:

$31+x+(x-15) = 180$

Let's solve for x.

Combine like terms:

$31+2x-15=180$

Add 15 to both sides:

$31+2x=195$

Subtract 31 from both sides:

$2x=164$

Divide both sides by 2:

$x= 82$

So x is 82°.

Hope this helped!
