Question

24. If cot A = 7/8, then find value of tanA. cotA
A) 8/7
B) 49/64.
C 1.
D) 7/8​

Answer 1

Step-by-step explanation:

cotA=7/8

then tanA=1/cotA=1/(7/8)=8/7

tanA.cotA=8/7×7/8=1(option C)

Answer 2

Answer:

cotA=7/8

we know tanA=1/cotA

so, we can put 1/cotA in place of tanA.

Now tanA. cotA = 1/cotA.cotA = 1

so correct answer is option C.(1)
