Question

tan theta are equal to 8 by 15 ho to cos theta ka man gyat Karen ​

Answer 1

Answer:

15/17

Step-by-step explanation:

tan ø= 8/15

tan= Perpendicular/Base

so Perpendicular is 8 and base is 15

now draw a right angled triangle

shown on the above picture

In the right angled ABC

AC²=AB²+BC²

AC²=(15)²+(8)²

AC²=225+64

AC²=289

AC=17

Therefore Perpendicular=8

Base=15

Hypotenuse=17

Therefore cos ø=Base/Hypotenuse

cos ø= 15/17
