Answer:
15 ft
Step-by-step explanation:
Hi, the illustration for the problem is a right triangle with:
hypotenuse (C)= the length of the ladder = L
horizontal side(A) = distance from bottom of the ladder to the building = L - 6
vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3
So, we can use Pythagoras formula:
A2 +B2= C2
(L – 6 )² + (L-3)² = L²
L²-12L+36+L²-6L+9 =L²
L2 -18L+45 =0
APPLYING QUADRATIC FORMULA WE OBTAIN:
L =15 OR L=3
If L=3
Vertical side = L-3 = 0 (Length can´t be 0)
So L=15
Answer:
73
Step-by-step explanation:
6x+25=10x-11
-4x=-36
x=8
6(8)+25
48+25=73
I am not sure on this one but hope I helped
Answer:
This question makes no sense but here we go:
Step-by-step explanation:
Assuming the sum must be equal to six:
x+y = 6
Comment if i'm getting the wrong idea, this question makes like no sense to me. Perhaps a grammatical error?
