Answer:
Please see picture below.
Step-by-step explanation:
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:
49.5 square inches
Step-by-step explanation:
We can split the figure into two easier shapes to find the area of; a triangle and a square.
The formula for a triangle is (b*h)1/2. Once we solve we get 24.5 or 24 1/2.
The formula for a square is l*w. Once we solve we get 25.
To find the area of the shaded region, we would add both area and get 49.5 or 49 1/2 square inches.
Answer:
p²-14p+49
Step-by-step explanation: To find the area of a square just multiply side x side. So (p-7)(p-7). Use FOIL or double distributive property to get p²-7p-7p+49 then combine the two middle terms to get p²-14p+49
