Question

if theta is in Q2 and sin theta =5/13 then find cot theta​

Answer 1

Answer:

$\huge\underline{\underline{\mathbb\pink{ANSWER}}}$

Explanation:

If θ were in Q1 then we would simply be dealing with the internal angles of a 5, 12, 13 right angled triangle.

Note that:

52+122=25+144=169=132

Hence in Q1 we would have:

sinθ=1213 and tanθ=125

In Q2, cosθ<0, so cannot be equal to 513, so there is an error in the question.

In Q4, we would find sinθ=−1213 and tanθ=−125.
