An 87 degree angle!
An acute angle measures 87 degrees
87 degrees
87 degrees is an acute angle because it is greater than 0 but less than 90 degrees
The same as the central angle of the circle
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
5th angle of the pentagon: 540-93-87-97-153 = 110 degrees
90 - 87 = 3 (half of the second angle)3 x 2 = 6 degrees (the second angle)90 - 6 = 84 degrees (first angle)
The fourth exterior angle is 93 degrees so the fourth interior angle must be 87 degrees because there are 180 degrees on a straight line.
An angle that measures 210 degrees is a reflex angle.
A right angle measures 90 degrees
The third angle measures 18 degrees.
To find the measurement of angle A in the triangle, we can use the fact that the sum of the angles in a triangle is always 180 degrees. Given that angle E measures 30 degrees, angle F measures 57 degrees, and angle B measures 27 degrees, we can calculate angle A as follows: Angle A = 180 - (angle E + angle F + angle B) = 180 - (30 + 57 + 27) = 180 - 114 = 66 degrees. Therefore, angle A measures 66 degrees.
