One of the angles formed at the intersection of two straight lines is four times smaller than the other. What is the degree measure of the larger of them?
The solution of the problem:
Adjacent corners are formed when two straight lines intersect. The sum of two adjacent angles is 180 degrees.
1. One of the adjacent angles is x degrees.
2. Find what the other angle is equal to.
x * 3 = 3x degrees.
3. Let’s compose and solve the equation.
x + 3x = 180;
4x = 180;
x = 180/4;
x = 45;
4. One adjacent angle is x = 45 degrees.
5. The second adjacent angle is x * 3 = 45 * 3 = 135 degrees.
Answer: One adjacent angle is forty-five degrees, the other adjacent angle is one hundred thirty-five degrees.
