Answer:
60 degrees
Step-by-step explanation:
We are given the measures of WY and XY. Using them, we can find out 2WY=XY.
In 30-60-90 right triangle, the hypotenuse is 2 times the shortest leg. This means that this triangle is a 30-60-90 triangle. Angle Y is the angle made by the shorter leg and the hypotenuse therefore it is 60 degrees.
Answer:
Option (4)
Step-by-step explanation:
Let x = ![\sqrt[4]{7}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B7%7D)
= (x)(x)(x)(x)
= 
= x⁴
Now we substitute the value x = ![\sqrt[4]{7}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B7%7D)
x⁴ = ![(\sqrt[4]{7})^4](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B7%7D%29%5E4)
x⁴ = 7
Therefore, Option (4) will be the answer.
just plug into a calculator
Answer: Infinite solutions.
Step-by-step explanation:

Plug the value of y into the second equation.

Add 12 on both sides.

Add 4x on both sides.
