The pythagorean theroem states that for a right triangle, a squared plus b squred equals c squared, where a and b represent the length of each of the legs and c represents the length of the hypotenuse.
Therefore the answer is D
Answer:
48.2°
Step-by-step explanation:
If a 15' ladder is leaned up against a building so that the bottom of the ladder is 10' from the base of the building, what angle does the ladder make with the ground
Let the angle the ladder makes with the ground be represented by x
We solve the above question using the Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = 10 inches
Hypotenuse = 15 inches
Hence,
cos x = 10/15
x = arc cos (10/15)
x = 48.189685104°
Approximately = 48.2°
Therefore, the angle the ladder makes with the ground is 48.2°
3n+2
the difference between each term is 3 meaning it’s 3n. if you then take away 3 from the first term you are left with 2. this means the nth term is 3n+2
2(x-7)/3=-2
3*2(x-7)/2*3=-2*3/2
x-7=-2*3/2
x-7=3*-1
x+(7-7)-7-3
x=7-3
x=4
Answer:
-11 =d
Step-by-step explanation:
22/d = -2
Multiply each side by d
22/d *d = -2*d
22 = -2d
Divide each side by -2
22/-2 = -2d/2
-11 =d
