PLZ SOLVE PIC ATTACHED BELOW

ludmilkaskok [199]

Answer:

$\tan(51°) = \frac{10}{x} \\x = \frac{10}{ \tan(51°) } \\ x = \frac{10}{1.235} \\ \boxed{ x = 8.1}$

<h3>★ Value of x is <u>8.1</u>.</h3>

$\sin(51°)= \frac{10}{H} \\ h = \frac{10}{ \sin(51°) } \\ H= \frac{10}{0.777} \\ \boxed{H= 12.8676}$

<h3>★ Value of H is <u>12.8676</u>.</h3>

Remember:

tan∅=Perpendicular/Base
sin∅=Perpendicular/Hypotenuse
