Question

WILL GIVE MEDAL!

Answer 1

\[\sin 35 = \frac{ opposite \ side }{ hypotenuse } = \frac{ x }{ 15}\]\[x = 15 \times \sin 35 = 15 \times = 8.60 = 8.6 m \]

got it :) ?

Answer 2

No, this is so confusing for me, I'm sorry.

Answer 3

now
\[\sin \theta = \frac{ opposite \ side }{ adjacent side }\]\[\cos \theta = \frac{ adjacent \ side }{ hypotenuse }\]\[\tan \theta = \frac{ opposite \ side }{ adjacent \ side }\]
these r called trignometric ratios and i hope u know about them,..... now in ur problem
