Question

Find the measure of the indicated angle to the nearest degree

Answer 1

$\boxed{\sf tan\theta=\dfrac{p}{b}}$

$\\ \sf\longmapsto tan\theta=\dfrac{13}{20}$

$\\ \sf\longmapsto tan\theta=0.6$

$\\ \sf\longmapsto tan\theta\approx\dfrac{1}{\sqrt{3}}$

$\\ \sf\longmapsto tan\theta\approx tan60$

$\\ \sf\longmapsto \theta\approx 60°$
