Question

Can someone help me with 5 and 6?

Answer 1

Sine = (opposite)/(hypotenuse). Cosine = (adjacent)/(hypotenuse). Tangent = (opposite)/(adjacent). Fill in the numbers. They're all on the drawing . Then memorize these definitions. You'll need them as long as you're in school, and possibly after.

Answer 2

First of all use SOH CAH TOA. Easiest way to memorize these. Now for the questions. I will do 5 only.

SIN: 6 root 2/19
COS: 17/19
TANGENT: 6 root 2/17
