Question

What’s the value of x worth 15 points!

Answer 1

Hi there! :)

Answer:

x=39

*The answer must have a positive sign.*

Explanation:

When the 2 acute angles in which means you had to used 2x from both sides of an equation.

First, only had to do is, add by 15 from both sides of an equation.

`3x-15+15=2x+24+15`

Then, you add by the numbers from left to right.

`24+15=39`

`3x=2x+39`

Next, you subtract by 2x from both sides of an equation.

`3x-2x=2x+39-2x`

Finally, you simplify.

`x=39`

Final answer is x=39

Hope this helps!

Thanks!

Have a nice day! :)

Answer 2

3x - 15 = 2x + 24
Opposite angles of a parallelogram are equal. You get a hint of that from the 2 acute angles which are both 2x.

Add 15 to both sides.
3x = 2x + 24 + 15
3x = 2x + 39 Subtract 2x from both sides.
3x - 2x = 39
x = 39
