42 adjacent angles with the measure x and x plus thirty that make up a ninety degree angle what is x

1 answer

To find the value of x, we need to solve the equation that represents the sum of the two adjacent angles being equal to 90 degrees.

Let's assume the measure of the first angle is x.

According to the given information, the measure of the second angle is x + 30.

Since adjacent angles add up to 90 degrees, we can write the equation:

x + x + 30 = 90

Combining like terms:

2x + 30 = 90

Subtracting 30 from both sides:

2x = 60

Dividing both sides by 2:

x = 30

Therefore, x is equal to 30.
