Answers

Answered by Sanjana111111

tan (3x-15) = 1

But tan 45 = 1

3x - 15 = 45

3x = 45 + 15

x = 20

vamsi61: 20

debjit27122000: tan(3x -15)=1
But tan45=1 when thita in first quartinate and tan225=1 when theta in 3rd quardinate.....so ...
3x-15=45 where x=20 but when 3x-15=225 where x=80.........
Am i right??

kagrawal: bhai srry i am in 10th standard

Sanjana111111: nd i am not able to get ur ans

kagrawal: i not understand which question you want to ask

debjit27122000: Which class u study??

debjit27122000: Agar 11 ma science laka paroga to jan payogi kaisa x=80 ho raha hai

tan 45 is 1 so 3x -15 = 45.....3x = 60......x =20
