Sin80=h/15

(because h is opposite the angle of elevation and 15 is the hypotenuse)

h=15sin80=14.77

h=14.8 ft  (rounded to the nearest tenth of a foot)

<h2>The height from the top of the ladder to the ground is 14.77 ft</h2>

Step-by-step explanation:

A ladder that is 15 feet long leans against the side of a house

Length of ladder = 15 feet

The angle of elevation of the ladder is 80°

Refer the given figure

We need to find height h.

We have

              sin80=\frac{h}{15}\\\\h=15\times sin80=14.77ft

The height from the top of the ladder to the ground = 14.77 ft

Some please help me in the bottom show me how to do it really confuse ....

use the equation (y-y)=m(x-x). for example with the first equation: (y-7)=-4(x-2) distribute the slope into the (x-2). this will give you (y-7)=-4x+8. then you add the 7 to both sides to cancel it. this gives you y=-4x+15. hope this helps!! :)

F(x) = 4x^2 + 3x - 11<br> f(-3)
Mnenie [13.5K]
Just plus in x for -3
f(x) = 4(-3)^2 + 3(-3) - 11
f (x) = 4(9) -9 - 11
f(x) = 36 - 20
f(x) = 16

Ber [7]
The answer is a.
Substitute (-2,1) and (1,10) into each answer. Only a is correct because you will get -7 from both points.
