1a) use the pythagorean theorem tofind the missing side length.
1b) write the sin, cosine and tangent of each angle leave answers in fractions. rationalize the denominator if needed.

Answer with step-by-step explanation:

1a) We are given a right angles triangle and we are to find the missing side length using the Pythagoras Theorem.

1b) Writing the sine, cosine and tangent for angles a and b:

sin a

cos a

tan a

sin b

cos b

tan b

answer;
