The sum of the measures of two adjacent angles forming a right angle is 90 degrees.
Let the measure of the first angle be x degrees.
The measure of the second angle is (x+30) degrees.
Therefore, we have the equation:
x + (x+30) = 90
Simplifying the equation:
2x + 30 = 90
Subtracting 30 from both sides:
2x = 60
Dividing both sides by 2:
x = 30
So, the measure of the first angle is 30 degrees, and the measure of the second angle is (30+30) = 60 degrees.
Therefore, the two angle measures are 30 degrees and 60 degrees.
The answer is option B.
A right angle is formed by two adjacent angles with measures of (x) degree and (x+30) degree. What are the two angle measures?
A. 70 degree and 25 degree
B. 30 degree and 60 degree
C. 75 degree and 105 degree
D. 60 degree and 90 degree
