Let us draw a picture to make the things more clear.
Attached is the image.
We have been given that

Therefore, we have

Now, in triangle bcd, we have

Now, in triangle acb, we have

Thus, ad is 15 cm.
Answer:
Step-by-step explanation:
Use the slope formula.
<h3 /><h3>What is a slope?</h3>
Slope is a surface with one end higher than the other and with no steps. It proceeds at an angle. The path sloped down to the beach.
So, the property possessed by a line or surface that departs from the horizontal.
<u>Slope formula:</u>
(-6,-2) (4,1)
<u>Rewrite the problem down.</u>

<u>Solve.</u>
1-(-2)=1+2
<u>Add.</u>
1+2=3
4-(-6)=4+6
4+6=10

Therefore, the slope is 3/10, which is our answer.

Answer:
A. in Step 3
Step-by-step explanation:
It is factored correctly. Then separated into two smaller equations correctly. But in solving x + 10 = 0, there is an error.
x + 10 = 0
Add -10 to both sides.
x = -10
So, the error is in step 3.
