Use the pythagorean theorem to find the missing side length. 2 write sin, cosine, tangent of each angel.

1)

2)

Step-by-step explanation:

 The Pythagorean Theorem is:

Where a is the hypotenuse and b and c are the legs.

The missing side lenght is one of the legs, then you must solve for one of them. Therefore, this is:

MEASURE OF ANGLE:

Keep the identities on mind:

Susbstitute values, then:

QUESTION 1

The missing side length is .

From the Pythagoras Theorem;

This implies that;

Take positive square root of both sides;

QUESTION 2

Rationalize the denominator to get;

d is correct
