A skateboard ramp has a 168 degree entry angle. Find the measure of angle 1 (1 point) Responses 22 degrees 22 degrees 78 degrees 78 degrees 12 degrees 12 degrees 68 degrees
If angle 1 is complementary to the 168-degree entry angle, then angle 1 would measure 180 degrees - 168 degrees = 12 degrees. Therefore, the correct answer is 12 degrees.
To find the measure of angle 1, we first need to know the sum of the angles in a triangle. In a triangle, the sum of the interior angles is always 180 degrees.
Since the entry angle of the skateboard ramp is 168 degrees, we can subtract this angle from 180 degrees to find the remaining angle.
180 degrees - 168 degrees = 12 degrees
Therefore, the measure of angle 1 is 12 degrees.
To find the measure of angle 1 in a skateboard ramp with a 168 degree entry angle, we need to know some properties of angles in a line and angles at a point.
1. Angles on a straight line: The sum of the angles on a straight line is equal to 180 degrees.
2. Angles at a point: The sum of the angles at a point is equal to 360 degrees.
Let's apply these properties to solve the problem:
1. Start with the given entry angle of 168 degrees.
2. Since the entry angle is a straight line, we subtract it from 180 degrees to get the remaining angle. 180 - 168 = 12 degrees.
3. Angle 1 is the same as the remaining angle we found in step 2.
4. Therefore, angle 1 measures 12 degrees.
So, the correct answer is 12 degrees.
