Use Pythagoras theorem
11^2 = h^2 + 3^2 where h is the height of ladder agaianst the wall
h^2 = 11^2 - 3^2
=(11+3)(11-3) = 14 * 8 = 112
h = sqrt 112 = 10.58 ft
Answer:
D is the answer.
Step-by-step explanation:
On edge, I took the test and put C the first time. I took the test again and D was the correct answer.
Answer:
10 feet
Step-by-step explanation:
base= x feet
height=(6+x) feet
area= (6+x)x=160
=6x+x²=160 ==> x²+6x-160=0
factories the eqn obtained....
(x-10)(x+16)=0
x= 10 or -16
since length cannot be negative, x=10
since the base = x feet
base=10 feet
