To find the value of x, we can set up an equation based on the given information.
The sum of two adjacent angles forming a straight line is always 180 degrees. In this case, the two angles form a 90-degree angle, which is half of 180 degrees.
So, we can set up the following equation:
x + (x + 30) = 90
Simplifying the expression, we get:
2x + 30 = 90
Subtracting 30 from both sides, we have:
2x = 60
Dividing both sides by 2, we get:
x = 30
Therefore, the measure of the smaller angle (x) is 30 degrees.
For two adjacent angles with measures x degrees and (x+30) degrees that make up a 90 degree angle, what is x?
