Answer:
1. tan(A) = 1.6071; tan(B) = 0.6222
3. tan(A) = 0.7500; tan(B) = 1.3333
Step-by-step 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
