Answer: (50,-20)
Step-by-step explanation:
Point B is (100,0).
Point A is (0,-40).
To find C you need the midpoint of both A and B, which means you add both coordinate x and coordinate y together to find the middle of both.
Midpoint of x coordinates:
100+0= 100
100÷2= 50
Midpoint of y coordinates:
0+(-40)= -40
-40÷2= -20
Therefore, point C is (50,-20)
B. First and Second St appear to be parallel
Answer:
78.5°
Step-by-step explanation:
We solve for the above question, using the formula for the Trigonometric function of Cosine
cos θ = Adjacent/Hypotenuse
Adjacent = The distance between the house and the base of the ladder = 4 feet
Hypotenuse = Length of the Ladder = 20 feet
Hence,
cos θ = 4/20
θ = arc cos(4/20)
θ = 78.463040967°
Approximately = 78.5°
Therefore, the angle that the ladder makes with the ground is 78.5°
