Question

if 8 tanQ=15 then sinq-cosq
​

Answer 1

Step-by-step explanation:

tanQ = 15/8

sinQ / cosQ = 15/8

sinQ = 15

cosQ = 8

sinQ - cosQ = 7

Answer 2

Answer:

7/17

Step-by-step explanation:

Tan Q= 15/8=perpendicular/base

sinQ=perpendicular/hypotenuse

cosQ=Base/hypotenuse

According to phytagoras theorem

(H)²=(P)²+(B)²

(H)²=(15)²+(8)²

(H)²=225+64

(H)²=289

H=17

sinQ=15/17

cosQ=8/17

sinQ-cosQ=15/17-8/17

15-8/17

→ 7/17
