Will give brainliest a bird fountain is located 6 m from the base of joey's apartment building. from his window, joey can see it at a 51 degree angle of depression. to the nearest tenth of a meter, how far up the building is joey's window? a) 4.9 m b) 7.4 m c) 7.7 m d) 9.5 m

Option B. 7.4 m.

Step-by-step explanation:

Angle of depression given = 51°

Distance of the fountain from the building = 6 m

We have to find the height of the window from the ground.

Now tan 51° = height of window/ distance of building from the fountain.

1.23 = height of window/6

height of window = 6×1.23 = 7.40 m.

Option B. is the answer.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

use this formula:

p(a\b) = p(a and b)/p(b).
