x +12°
х
35°
3 x-10°​

Answer 1

Step-by-step explanation:

Find the measures of all the angles of the given figure:

n stands for the number of sides, which is 4.

To find the sum of the angles, subtract 2 from the number of sides and multiply by 180.

Add all the angles together and set that equal to 360 to solve for x.

Plug 32 ° in for x to find the measures of the angles.

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
