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)=(12)/(30)`

now, we can take smaller triangle to find h

`sin(t)=(h)/(20)`

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

and we get

`(12)/(30)=(h)/(20)`

now, we can find h

`h=20*(12)/(30)`

`h=8ft`..............Answer
