Answer:
41/60
Step-by-step explanation:
Convert the fractions into like denominators: 7/30 = 140/600, 9/20 = 270/600
Add: 140/600+270/600 = 410/600
Divide into a smaller fraction: 41/60
55
To start to solve this problem we start by observing what information there is. We need y, to find y we have to know x. We need x to find y because all the angles in a triangle add up to 180. If we find x we can subtract the angles we know and get y. To find x we look and see that it is on a straight line, and on the other side of the line is 100. We know that a straight line is 180 degrees so we subtract 100 from 180 to get x. We now know x is 80, so now we minus 89 and 45 from 180. We get 55. This means that y is 55.
Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.

Step-by-step explanation:
![\sin(x + 7) = \cos(4x + 8) \\ \sin(x + 7) = \sin \{90 - (4x + 8) \} \\ \{ \because \cos \theta = \sin(90 \degree - \theta) \}\\ \therefore \: (x + 7) = 90 - (4x + 8) \\ x + 7 + 4x + 8 = 90 \\ 5x = 90 - 15 \\ 5x = 75 \\ x = \frac{75}{5} \\ x = 15](https://tex.z-dn.net/?f=%20%5Csin%28x%20%2B%207%29%20%3D%20%20%5Ccos%284x%20%2B%208%29%20%5C%5C%20%20%5Csin%28x%20%2B%207%29%20%3D%20%20%5Csin%20%5C%7B90%20%20-%20%284x%20%2B%208%29%20%5C%7D%20%5C%5C%20%20%5C%7B%20%5Cbecause%20%5Ccos%20%5Ctheta%20%3D%20%20%5Csin%2890%20%5Cdegree%20-%20%20%5Ctheta%29%20%20%5C%7D%5C%5C%20%20%5Ctherefore%20%5C%3A%20%28x%20%2B%207%29%20%3D%2090%20-%20%284x%20%2B%208%29%20%5C%5C%20x%20%2B%207%20%2B%204x%20%2B%208%20%3D%2090%20%5C%5C%205x%20%3D%2090%20-%2015%20%5C%5C%205x%20%3D%2075%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B75%7D%7B5%7D%20%20%5C%5C%20x%20%3D%2015)
(x + 7)° = (15 + 7)° = 22°
(4x + 8)° = (4*15 + 8)° = (60 + 8)° = 68°
Answer:
The probability of randomly picking a red candy is 1/20 and In percentage value 5%
Step-by-step explanation:
There are 5 blue candies, 6 red candies, and 9 yellow candies.
Now, Total
5 + 6 + 9 = 20 candies
Now, The probability of randomly picking a red candy is 1/20
Now, In percentage
1/20 × 100% = 5%
Thus, The probability of randomly picking a red candy is 1/20 and In percentage value 5%.

Answer: the formula is : β = 180° - α
A = 6 * a² * sin(α)
V = a³ * (1-cos(α)) * √1+2cos(α)
