Question

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

What is sin x
And
What is tan x

Answer 1

Answer:

$\sf sin(x) = \dfrac{5}{8}$   and  $\sf tan(x) = \dfrac{5}{7}$

Given sides:

• hypotenuse: 8

• opposite: 5

• adjacent: 7

Sine rule given by:

$\sf sin(x) = \dfrac{opposite}{hypotenuse}$

$\sf sin(x) = \dfrac{5}{8}$

Cosine rule given by:

$\sf cos(x) = \dfrac{adjacent}{hypotenuse}$

$\sf cos(x) = \dfrac{7}{8}$

Tan rule given by:

$\sf tan(x) = \dfrac{opposite}{adjacent}$

$\sf tan(x) = \dfrac{5}{7}$
