Pls help me find each measure on 1-8

9514 1404 393

Step-by-step explanation:

The diagonals of a rhombus are perpendicular bisectors of each other.

__

1. KY is the long leg of right triangle KYR, whose hypotenuse is given as 13 and short leg as 5. If you do not recognize this as a 5-12-13 right triangle, you can find the longer leg using the Pythagorean theorem.

  KY² +RK² = RY²

  KY² = RY² -RK² = 169 -25 = 144

  KY = √144 = 12

__

2. K is the midpoint of diagonal PY, so PK = KY = 12.

__

3. As we have said, the diagonals cross at right angles.

  m∠YKZ = 90°

__

4. PZ is parallel to RY, so the alternate interior angles created by diagonal ZR are congruent.

  m∠PZR = m∠YRZ = 67°

_____

5. We recognize that hypotenuse PQ of right triangle PQA is √2 times the side length AP. So, this is a "special right triangle" that is isosceles. The sides and hypotenuse have the ratios 1 : 1 : √2.

  AQ = AP = 3

__

6. As in any isosceles right triangle, the acute angles are 45°.

  m∠APQ = 45°

__

7. Each of the smaller acute angles is 45°. The diagonals bisect the corner angles, so each corner angle is 2×45° = 90°.

  m∠MNP = 90°

__

8. A is the midpoint of PM, so PM is twice the length of AP.

  PM = 2×AP = 6

1. 3

2. 4
