Answer: C and D

Step-by-step explanation: SO what you need to do here is pick any number to plug in as y let’s say 2. 7+(5*2)=17 and then you solve for the next equation using 2. (7+5)*2=24. Now we know its not a. Let’s do b (12-4)*2=16 and 12-(4*2)=4 that can’t be it. Now c 8+(2*3)=14 and 8+(3*2)=14. Now D (11/2)+6=11.5 and 6+(2/11)= 11.5. You can use any number to plug in.

ikadub [295]

Answer:

Angle made by ramp with ground is ≈19.29^{\circ}

Step-by-step explanation:

Diagram of given scenario is shown below.

Given that,

Horizontal Distance of Skateboard ramp is 10 ft.

Height of Skateboard ramp is 3.5 ft.

From figure,

It is forming a Right angle triangle \triangle ABC.

In \triangle ABC, AB=3.5 and BC=10.

Clearly see that we need to find measure of angle \angle C.

Using Trigonometric ratio:

     Tan(\theta)= \frac{Perpendicular}{Base}

So,  Tan(\angle C) = \frac{AB}{BC} =\frac{3.5}{10} =0.35

Then \angle C=Tan^{-1} (3.5)=19.290046^{\circ}

Therefore, Angle made by ramp with ground is ≈19.29^{\circ}
