Question

Can someone please help me with trigonometry?
Ill give out brainliest~
Just provide work and awnsers for #2 and #3! Thanks so much!!​
(Also ignore writing I'm not sure what I'm doing...)

Answer 1

(2) sin=op/hy

$sin = \frac{4 \sqrt{3} }{13}$

=0. 5329 but one decimal place

So,
=0. 5

(3)

$sin = \frac{7}{9} \\ = 0.7 78$

$cos = \frac{x}{9} or \ \: cos = \frac{0.778}{9} \\ tan = \frac{7}{x} \: or \: tan = \frac{7}{0.778}$

I think............

I don't understand number 3 Either
