Step 1

Given that theta is in quadrant 2 and sine theta value is given to us. We need to compute cos theta using pythogorean identity and then find tan theta using Quotient Identity.

Step 2

Here the pythogorean Identity is shown below we know the value of sinθ and we use it to find the value of cosθ

Step 3

We got cos θ value as shown below but we need to confirm its sign.

Here it is said that θ is in quadrant 2, so the sin &theta...
