12. for triangle mnp shown, find the value of x
and the measure of each of the three angles
m
/(2x – 1)º (2x + 1))

Step-by-step explanation:

Given:

The triangle is shown below.

We know that the sum of all interior angles of a triangle is equal to 180°.

Therefore,

Now, plugging the value of 'x' in each angle measure and determining its values. We get:

Therefore, the value of 'x' is 36° and the measure of the three angles are 36°, 71° and 73°.

i belive those are the ones that are under 90 degreese.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
