(adsbygoogle = window.adsbygoogle || []).push({}); 1. If sinA=7/25 and sinB=5/13, where A is acute and B is obtuse, find the exact value of tan(A+B)

2. Tan(A+B)=tanA+tanB/1-tanAtanB

3. TanA=7/24

TanB=5/-12

Tan(A+B)=7/24+5/-12/1-7/24x5/-12=-36/323 or -0.1 (1d.p.)

Could somebody please check this for me, please?
