Answer:

10, 8.66 and 5

There are two fundamental relations between sides of a right triangle when its angle equals to 60 degrees. The length of adjacent side is equal to half of the length of hypotenuse. The length of opposite side is equal to √3/2 times of the length of hypotenuse. The third angle of right triangle is 30∘ .

Step-by-step explanation:

The exact measurement cannot be determined, but if we suggest hypotenuse is 10, adjacent (half) would be 5, and then based on 30 degree angle then opposite side will be 10√3/2 = 8.66.

Step-by-step explanation:

Since m∠ACM = 90°, then by angle addition, m∠ACP + m∠PCM = 90°.
Since CP⊥ AM, then by definition of perpendicular, m∠APC = 90°. Since angles of a triangle add up to 180°, that means m∠PAC + m∠ACP = 90°.
By substitution, m∠PCM = m∠PAC.
Since m∠PCM + m∠CMP = 90°, then by substitution, m∠CMP = m∠PAC.
Therefore, by AAA, △ACP and △CMP are similar.

Having proven that the triangles are similar, we can write the proportion:

AP / CP = CP / MP

9 / CP = CP / 16

CP² = 144

CP = 12

Now, we can simply use Pythagorean theorem to find the other sides.

AC² = AP² + CP²

AC² = 9² + 12²

AC = 15

CM² = CP² + PM²

CM² = 12² + 16²

CM = 20
