Dear Student
Given function: cos θ = 7/25
We know that cos θ = AB/AC = Base/Hypotenuse = 7/25
By Pythagoras Theorem:
AC^2 = AB^2 + BC^2
BC^2 = AC^2 - AB^2
= 625k^2–49k^2
= 576k^2
AB = 24k
Find other T-rations using their definitions:
Sin𝜃= BC/AC = 24/25
Tan𝜃= BC/AB = 24/7
cosec 𝜃= 1/sin𝜃= 25/24
sec𝜃= 1/cos𝜃= 25/7
cot𝜃= 1/tan𝜃= 7/24
Thanks
