To find the measure of two adjacent angles that make up a 90-degree angle, we can use the fact that the sum of angles in a right triangle is 90 degrees.
Let's assume the measure of the first angle is x. The measure of the second angle is (x + 30) since they are adjacent.
According to the given information, the sum of these two angles equals 90 degrees:
x + (x + 30) = 90
Combining like terms:
2x + 30 = 90
Subtracting 30 from both sides of the equation:
2x = 90 - 30
2x = 60
Dividing both sides by 2:
x = 60/2
x = 30
Therefore, the measure of the first angle (x) is 30 degrees.
For two adjacent angels with measure x and (x+30) that make up a 90 angle what is x?
