Answer:
35 degrees
Step-by-step explanation:
The law of reflection states that the angle of reflection equals the angle of incidence, or
So, if 
So, Angle of incidence will also be equal to 35 degrees.
If you multiply $60 by 0.15 you'll get 9 which is the taxes of the meal. Since he leaves the same percentage of tip, now we add 9+9 and get $18..
60+18=78
Answer:
12.4
Step-by-step explanation:
First you need to find the hypotenuse of the other triangle, because it makes up a necessary side for finding AD. Pythagorean theorem states that
a^2 + b^2 = c^2 where a and b are leg lengths and c is the hypotenuse. For the triangle on the left, you're given 2 legs. So you can substitute those into that formula:
a^2 + b^2 = c^2
(10)^2 + (6)^2 = c^2
100 + 36 = c^2
136 = c^2.
Now take the square root of both sides to isolate c.
11.6619038 = c.
11.6619038 rounds to 11.7 so c = 11.7
Now that you have the second leg length for the triangle on the right, you can find its hypotenuse.
Follow the same process. Substitute your values into the equation and then solve for c:
a^2 + b^2 = c^2
(11.7)^2 + (4)^2 = c^2
136.89 + 16 = c^2
152.89 = c^2
Now find the square root of both sides to isolate c
12.3648696 = c.
12.3648696 rounds to 12.4 so c = 12.4
So the distance of AD is 12.4
The probability that two events occur is equal to the product of the individual events happening or occurring. For this item, we let x be the probability that is unknown such that the relationship between them may be expressed as,
(3/5)(x) = 33/95
The value of x from the equation is 11/19.
