PLEASE HELP IM DESPERATE

Answer 1

`\frac{sqrt{5} }{3}`

Explanation:

Its root 5 over 3

Answer 2

• cos (90 - m)° = 2/3

--------------------------------------

If m° is one of the angles of a right triangle, the complementary angle is (90 - m)°.

We know that sine of the angle is same as the cosine of the complementary angle. It means:

• sine m° = cos (90 - m)°

Therefore the value of cos (90 - m)° is 2/3.
