Question

if tan5q. tan4q =1 then q =​

Answer 1

Answer:

Ans is 10

Step-by-step explanation:

Tan5A .tan4A=1

tan5A = 1/ tan4A _____ (1/tanA =cotA)

tan5A=cot4A ______(cotA =tan(90-A)

tan5A=tan (90 - 4A)

5A=90 -4A

5A+4A=90

9A =90

A=10

hope this answer helpful

I just take A for q .

Answer 2

Answer:

when we do a questions we make a BODMAS mean B - Braket , O - Of , D - Divide , M - Multiplication, A - Addition , S - Subration

now we take first sine like that D,M,A,S

1. Example - 5+7+8×9÷0÷2=4×6÷3-6-8-4we Divide sine like D-9÷0,6÷3,2÷0 we solve these questions
2. like M-8×9,4×6 solve these questions
3. like A-5+7,7+8 solve these question
4. like S-3-6,6-8,8-4
