Question

If sinθ =
_7_ find the value of cosθ
25

please answer this question ​

Answer 1

Step-by-step explanation:

Given that

sin(thita) =7/25

but we know that

sin(thita)= perpendicular/hypotenuse

so perpendicular/hypotenuse= 7/25

by Pythagoras theorem

(hypotenuse)²=(base)²+(perpendicular)²

(25)²=(base)²+(7)²

so (base)²=625-49

(base)²=576

so base= ±√576

base=24

so , cos(thita)=Base/hypotenuse

cos(thita)= 24/25.
