The angle measure of ACB is 9 degrees

Answer: Option B

<u>Step-by-step explanation:</u>

To find the solution to the given problem, first we need to look into the point B. It consists two angles and both of them are on a straight angle. So, this means that the sum of angle ABC and CBD is 180 degrees, that is

$\angle A B C+\angle C B D=180^{\circ}$

We know that $\angle C B D=29^{\circ}$ . Therefore

$\angle A B C+29^{\circ}=180^{\circ}$

$\angle A B C=180^{\circ}-29^{\circ}=151^{\circ}$

Now, in the triangle ABC, we know that all three angles must sum 180 degrees,

$\angle C A B+\angle A B C+\angle B C A=180^{\circ}$

$20^{\circ}+151^{\circ}+\angle B C A=180^{\circ}$

$\angle B C A=180^{\circ}-20^{\circ}-151^{\circ}=9^{\circ}=\angle A C B$

Therefore, the angle ACB is 9 degrees.

igomit [66]

5 is a constant - you pay $5 before you go on any of the waterslides.
let the number of waterslides Steven went on = x

5 +2x =17 ($5 plus $2 per waterslide ride = 17)

Answer a is correct.
By the way, Steven went on 6 waterslide rides.
