Answer:
y=-2x+5
Step-by-step explanation:
<u>Given</u>:
The given triangle has three equal sides. Thus, the given triangle is an equilateral triangle.
The measure of one angle is (4x - 20)°
Since, it is an equilateral triangle, then all the three sides will be equal.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the triangle sum property.
Thus, we have;
![(4x-20)^{\circ}+(4x-20)^{\circ}+(4x-20)^{\circ}=180^{\circ}](https://tex.z-dn.net/?f=%284x-20%29%5E%7B%5Ccirc%7D%2B%284x-20%29%5E%7B%5Ccirc%7D%2B%284x-20%29%5E%7B%5Ccirc%7D%3D180%5E%7B%5Ccirc%7D)
Simplifying, we have;
![4x-20+4x-20+4x-20=180](https://tex.z-dn.net/?f=4x-20%2B4x-20%2B4x-20%3D180)
Adding the like terms, we have;
![12x-60=180](https://tex.z-dn.net/?f=12x-60%3D180)
![12x=240](https://tex.z-dn.net/?f=12x%3D240)
![x=20](https://tex.z-dn.net/?f=x%3D20)
Thus, the value of x is 20
