Given the following diagram, find the missing measure. given: m p = m 2; m p = 30 45 60 90

Step-by-step explanation:

If m∠P = m∠2 then it's an isosceles triangle.

m∠M = 90°, therefore it's an isosceles right triangle.

We know, the sum of measures of angles in a triangle is equal 180°.

Therefore we have the equation:

m∠P + m∠2  + m∠M = 180°

Substitute m∠M = 90° and m∠P = m∠2 = x:

x + x + 90° = 180°      substract 90° from both sides

2x = 90°       divide both sides by 2

x = 45° → m∠P = 45°

answer: group b.

step-by-step explanation:

the correct answer for this just to make it clear for you guys is 2,3
