Question

Find the value of h in the triangle

Answer 1

Firstly , we need to locate some unknowns

we can find angle t

Let's take bigger triangle first

$sin(t)=\frac{12}{30}$

now, we can take smaller triangle to find h

$sin(t)=\frac{h}{20}$

now, we can plug value of sin(t) here

and we get

$\frac{12}{30}=\frac{h}{20}$

now, we can find h

$h=20*\frac{12}{30}$

$h=8ft$..............Answer
