Find the measure of the indicated angle to the nearest degree.​
Paladinen [302]

Using Pythagorean triplete

\\ \sf\longmapsto h^2=33^2+8^2

\\ \sf\longmapsto h^2=1089+64

\\ \sf\longmapsto h^2=1153

\\ \sf\longmapsto h=\sqrt{1153}

\\ \sf\longmapsto h=33.9

\\ \sf\longmapsto h\approx34

Now

\boxed{\sf sin\theta=\dfrac{h}{P}}

\\ \sf\longmapsto sin\theta=\dfrac{34}{8}

\\ \sf\longmapsto sin\theta=4.2

\\ \sf\longmapsto 2sin\theta=sin60

\\ \sf\longmapsto \theta=30°
