Answer:
65/72
Step-by-step explanation:
Given that ∠T=90° then the triangle ΔRST is a right angled triangle. Considering ∠S, RT is the opposite side, TS is the adjacent side and RS is the hypotenuse side. Using the notation
SOH CAH TOA
Tan ∠S = 72/65
Hence the cotangent of ∠S which is the inverse of the tangent will be
= 65/72
Answer:
20
Step-by-step explanation:
