Question

Trig.

A triangle with the measurements
Hypo: 8
Opp: 5
Adj: 7

What is sin x
And
What is tan x

Answer 1

`\sf sin(x) = (5)/(8)` and
`\sf tan(x) = (5)/(7)`

Given sides:

• hypotenuse: 8

• opposite: 5

• adjacent: 7

Sine rule given by:

`\sf sin(x) = (opposite)/(hypotenuse)`

`\sf sin(x) = (5)/(8)`

Cosine rule given by:

`\sf cos(x) = (adjacent)/(hypotenuse)`

`\sf cos(x) = (7)/(8)`

Tan rule given by:

`\sf tan(x) = (opposite)/(adjacent)`

`\sf tan(x) = (5)/(7)`
