Question

given that 8 tantheta =15 find sintheta-costheta and also find sectheta ​

Answer 1

Answer:

1.7/17

2.17/8 is the answer

Answer 2

Step-by-step explanation:

tanO = 15/8 = perpendicular/base

Hypotenuse = √(base)²+(perpendicular)²

H = √(8)²+(15)² = √(64+225)

H = √289 = 17

SinO = P/H = 15/17

CosO = B/H = 8/17

Now ,

SinO - CosO = (15-8)/17 = 7/17

SecO = 1/CosO = 17/8
