From the image attached, we can see that the length of 17 1/2 ft corresponds to the hypotenuse in a right triangle, the length of 3 1/2 ft corresponds to the opposite side.

We can use the fact that the sin(θ) = $\frac{Opposite}{Hypotenuse}$ to find the angle that the ramp makes with the ground.

$sin(\theta)=\frac{3.5}{17.5}$

The angle is equal to

$\theta = sin^{-1}(\frac{3.5}{17.5} )\\\theta = 11.54\°$

LaToya had a large collection of basketball cards. She decided to give half of them to her friends, Aaron, and a fourth of them

Savatey [412]

1-1/2-1/4=1/4 If 75 is 1/4, then just divide to get the whole thing. 75/1/4=200
She had two hundred cards to start with. Hope this helps!!!

a ladder 30 decimeters long is leaning against the side of a building. the ladder makes an angle of 25 degrees with the side of

ozzi

H=how far up from the ground does the ladder touch the building
h/30=sin 25°
h=30 sin 25°
h=12.7 decimeters(1 decimal place)
Answer: The height that the ladder touch the building far up from the ground is 12.7 decimeters.
