X = 80
y = 85
If you look at only the left triangle, you can see that x is part of one of the angles. The 3 interior angles of the triangle add up to 180 degrees, so subtracting the other two angles, you get x + 30 = 110, or x = 80.
The same method can be used for the other triangle to find y.
Answer:
8
Step-by-step explanation:
The intersecting chord theorem is expressed as;
7 * x = 4 * 14
7x = 56
Divide both sides by 7
7x/7 = 56/7
x = 8
Hence the value of x is 8
Answer:
Step-by-step explanation:
![\frac{1}{\sqrt[5]{7}}=\frac{1}{7^{1/5}}=7^{-1/5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%5B5%5D%7B7%7D%7D%3D%5Cfrac%7B1%7D%7B7%5E%7B1%2F5%7D%7D%3D7%5E%7B-1%2F5%7D)
Answer:
k = 2
Step-by-step explanation:
subtract 9 from both sides and you have 3k=6
then divide by three on both sides to get 2
