Ireally need 99 points a 9 foot ladder leans against a building the foot of the ladder is 3 feet away from the building if a 6-foot ladder is propped against the building at the same angle with the ground the foot of the new ladder would be how far away from the building

2'

Step-by-step explanation:

ladder, bldg wall n ground form a triangle

cuz the two ladders are at the same angle

the two triangles are similar

their sides are in the same ratio:

9:6 = 3:x where x is the distance from bldg of the 6' ladder

x=3*6/9

= 2'

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
