What is the value of x? enter your answer in the box.

We can Notice that the Angles in the Given Triangle ABC are Equal

The Given Triangle ABC is an Equilateral Triangle

We know that an Equilateral Triangle has Equal Sides

let us take any two sides

AC = BC

4x - 30 = 2x + 20

2x = 50

x = 25

Verification :

we got x = 25

AC = 4x - 30 = 4(25) - 30 = 100 - 30 = 70

BC = 2x + 20 = 2(25) + 20 = 50 + 20 = 70

AB = 3x - 5 = 3(25) - 5 = 75 - 5 = 70

We Got All sides Equal to 70

So, x = 25 is correct value

if x decreases by 4 then y increases by 10

step-by-step explanation:

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
