Recall that all three angles in a triangle equals 180.
Knowing this, we just have to add up all the angles and figure out what the value 'x' is.
(x-22 + x-17 + 3x+19) = 180
Simplify:
5x - 20 = 180
Add 20 to both sides:
5x = 200
Divide both sides by 5:
x = 40
Now that we found the value for x, we need to solve for angle A.
Simply input the value of 'x' into angle A's equation:
40 - 22 = 18
Angle A = 18 degrees
Good luck! If you need me to explain anything, just ask :))

Answer:
2.07 or 13.57
Step-by-step explanation:
First, you'd want to calculate the total bill. So you'd do the original bill multiplied by 1.18 (signaling the addition of the tip).
46 · 1.18 = 54.28
If you're calculating only the tip, it would be 46 · 0.18= 8.28
Then, since there is Martha, and 3 of her friends, you'd divide the bill (54.28) by 4 people. However, since the question is a little unclear on whether it is asking how much each person should leave for the tip, or leave overall, there are 2 possible answers.
Overall, each person would leave 54.28/4 = 13.57.
For the tip only, each person would leave 2.07.
M = 24
To solve that you divide 42/7 which is 6 then you multiply 4*6 and you get 24
So
1/x * 3/8 = 5/8
1/x = 5/8 / 3/8
1/x = 5/3
x = 3/5
3/5 as a decimal is 0.6
Answer:
50/96
Step-by-step explanation:
I assume the table is:
![\left[\begin{array}{cc}Result&Total\\1&15\\2&13\\3&16\\4&17\\5&15\\6&20\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7DResult%26Total%5C%5C1%2615%5C%5C2%2613%5C%5C3%2616%5C%5C4%2617%5C%5C5%2615%5C%5C6%2620%5Cend%7Barray%7D%5Cright%5D)
Even numbers are 2, 4, and 6. The total number of times she rolled an even number is 13 + 17 + 20 = 50.
So the probability is 50/96.
