Answer:

(b) 1:9

Step-by-step explanation:

(b) x*y : kx*ky, so 1:k² with k=3 is 1:9

(c) Assuming the rectangles get a z dimension, the volumes would have a ratio of xyz : xkykzk = xyz : xyzk³ = 1 : k³. With k=2 that is 1:8. But the z was never introduced so this is a bit inconclusive.

Find the shaded area ..

never [62]

Answer:

39°

Step-by-step explanation:

The angle adjacent to 115° in the lower triangle = 180° - 115° = 65°

angle on circle in lower triangle

= 180° - (65 + 76)° ← angle sum in triangle

= 180° - 141° = 39°

Angles on the circle subtended from the same arc are congruent, then

shaded angle = 39°

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
