Answer:

40 degrees

Step-by-step explanation:

2x-30+x=90

Then you add x to 2x which will be 3x so now its

3x-30=90

add 30 to both sides

3x=120

divide 3 from both sides

x=40

Since Angle QPR is virticle to 2x-30+x=90

Angle QPR is 40 degrees

Calculate the angle of depression, x, if the boat is 750 ft. away from the light house and the light house is 300 ft high. Round

I am Lyosha [343]

Firstly , we need to draw diagram

we are given

opposite =300

adjacent =750

now, we can use tan formula

$tan(x)=\frac{300}{750}$

now, we can find x

$x=tan^{-1}(\frac{300}{750})$

we get

$x=21.8 degree$

so,

angle of depression is 21.8 degree.....Answer
