Here three sides of a right angled triangle given.
The three sides are b, 8 and 14.
The side with length 14 is the hypotenuse here. We have to find the side of length b.
To get b, we will use Pythagoras theorem here.
By using Pythagoras theorem we can write,
, where c is the hypotenuse.
So here we can write,



To solve it for b, now we have to move 64 to the left side by subtracting it from both sides.



Now to find b, we have to take square root to both sides. We will get,





We have got the required answer for the side b.
Answer:
D)DE=24 YD.;EF=10yd
Step-by-step explanation:
AB=12 FT SO YOU DO 12*2 AND YOU GET 24 ON DE
CB=5 FT SO YOU DO 5*2 AND YOU GET 10
I JUST HAD THE QUIZ I GOT IT RIGHT I JUST DIDNT EXAPLIN HOW I GOT IT IN A RIGHT WAY BAD WORDING.
It is a negative graph and if you take the peak- the y intercept, it gives you the value of b. make that value negative and you should get your answer. i also put my answer in the comments if you wanted it, but you said you didn’t so..
