Answer:
6, -5
Step-by-step explanation:
It's A 7^7
This is because if two numbers with the same base divide,we subtract the exponent of the divisor from that of the dividend
120 ÷ 3 = 40
tanA=8/15 and tan B=40/9
tan(A+B)=(tanA+tanB)/1-tanAtanB
(8/15+40/9)/1-(8/15×40/9)
=-672/185
Answer:15 / 1/4 = 3.75
