I need help with Finding x
ASAP!!!

The value of x in the triangle is 36°.

Step-by-step explanation:

Step 1:

The sum of all the angles in any triangle is equal to 180°.

We have all three angles in terms of x. The sum of the three angles in terms of x will be 180°.

So the angles of the triangle are 2x°, 2x°, and x°.

Step 2:

Now, we substitute all the angles to a sum of 180° to determine the value of x.

So x = 36°.

The angles of the triangle are 72°, 72°, and 36°.

Step-by-step explanation:

Given

3x - 4y = 12

To find the x- intercept let y = 0 in the equation and solve for x

3x - 4(0) = 12

3x = 12 ( divide both sides by 3 )

x = 4 ← x- intercept ⇒ (4, 0 )

To find the y- intercept let x = 0 in the equation and solve for y

3(0) - 4y = 12

- 4y = 12 ( divide both sides by - 4 )

y = - 3 ← y- intercept ⇒ (0, - 3 )
