Answer: The foot of the ladder is 10 feet away from the base of the wall.
Explanation:
Here , the wall , top and foot of the ladder and ground makes aright triangle of which length of ladder h=20 is regarded as hypotenuse, angle with ground is θ=600;cosθ=h or cos 60=b 20 or b = 20⋅cos 60=20⋅12=10 feet.
Answer:
I think it is -5
I am actually not sure
Step-by-step explanation:
Answer:56 degrees
Step-by-step explanation: Using Base Angles Theorem, we can conclude that angle x is 180-62*2, which is 180-124, which is 56 degrees.
Answer:
P (not green) = 17/20
Step-by-step explanation:
Given the following number of marbles:
Green : 3
Yellow : 4
Blue : 5
Pink :8
Total number of marbles = 3 + 4 + 5 + 8 = 20 marbles
if we draw 1 marble at random from the bag, the probability that the marble IS green,
P(Green) = 3/20
The probability that the marble is NOT green is,
P(Not Green)
= 1 - P(Green)
= 1 - 3/20
= 17/20
