Question

Find the measure of the indicated angle to the nearest degree

Answer 1

• B=8
• H=16

We know

$\boxed{\sf cos\theta=\dfrac{B}{H}}$

$\\ \sf\longmapsto cos\theta=\dfrac{8}{16}$

$\\ \sf\longmapsto cos\theta=\dfrac{1}{2}$

$\\ \sf\longmapsto cos\theta=cos60$

$\\ \sf\longmapsto \theta=60$
