Question

I need help with 1 and 3 please

Answer 1

1. tan(A) = 1.6071; tan(B) = 0.6222

3. tan(A) = 0.7500; tan(B) = 1.3333

Explanation:

The mnemonic SOH CAH TOA reminds you that the tangent is the ratio ...

Tan = Opposite/Adjacent

Then ...

Tan(A) = BC/AC

Tan(B) = AC/BC

___

1. tan(A) = 45/28 ≈ 1.6071

tan(B) = 28/45 ≈ 0.6222

___

3. tan(A) = 9/12 = 0.7500

tan(B) = 12/9 ≈ 1.3333
