Answer:
1.7
Step-by-step explanation:
( 5x + 2y = 7 ) 2
( - 2x + 6y = 9 ) 5
10x + 4y = 14
-10x + 30y = 45
----------------------
34y = 59
y = 1.7
Cosα=x/L
L=x/cosα, we are told that the ladder base is 48 ft from the base of the wall and α=39° so:
L=48/cos39 ft
L≈61.76 ft (to nearest hundredth of a foot)
Answer:
7
Step-by-step explanation:
The area for a parallelogram is given by the following formula:
Where b is the base and h is the height.
We already know the area is 28 and the height is 4. So, substitute:
Divide both sides by 4:
So, the base length is 7.
Our answer is 7 :)
