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°
Answer:
7/8 is the value of a
Step-by-step explanation:
1= 8a-6
8a = 7
a = 7/8
Answer:

Answer:
4 > x
Step-by-step explanation:
5 (x + 3) - 4> 3x + 9 + 4x – 6
5x + 15 - 4 > 3x + 4x + 9 - 6
5x + 11 > 7x + 3
11 - 3 > 7x - 5x
8 > 2x
8/2 > x
4 > x
Hope this helps :D
