5x−2 + 3x+4=90
5x−2 + 3x+4=90
5x−2 +90= 3x+4
5x−2 +90= 3x+4
5x−2 = 3x+4
5x−2 = 3x+4
5x−2 + 3x+4=180
The correct equation to find the value of x is:
5x - 2 + 3x + 4 = 90
The equation that could be used to find the value of x is:
5x - 2 + 3x + 4 = 90
To find the value of x, we need to use the fact that ∠A and ∠B are complementary angles, meaning they add up to 90 degrees.
The equation that can be used to find the value of x is 5x - 2 + 3x + 4 = 90.
Here's how you can set up the equation:
- The measure of ∠A is given by 5x - 2.
- The measure of ∠B is given by 3x + 4.
- Since ∠A and ∠B are complementary angles, their measures add up to 90 degrees.
So, we can write the equation as:
5x - 2 + 3x + 4 = 90
Now you can solve this equation to find the value of x.
