How do you solve for a side in a right triangle that has a hypotenuse of 10, an angle of 35, and the side across from the angle
goblinko [34]

\sin \theta = \dfrac{\textrm{opposite}}{\textrm{hypotenuse}}

\sin 35^\circ = \dfrac{x}{10}

x = 10 \sin 35^\circ

That's the exact answer; they usually want a calculator approximation at this point,

x \approx 5.735
