You can measure angles in degrees. However, The other common measurement for angles is radians. For this measurement, consider the unit circle (a circle of radius 1) whose center is the vertex of the angle in question. Then the angle cuts off an arc of the circle, and the length of that arc is the radian measure of the angle. It is easy to convert between degree measurement and radian measurement. The circumference of the entire circle is 2 ( is about 3.14159), so it follows that 360° equals 2 radians. Hence, 1° equals /180 radians, and 1 radian equals 180/ degrees.
Most calculators can be set to use angles measured with either degrees or radians. Be sure you know what mode your calculator is using.
55 degrees
The other three angles will each measure 120 degrees.
the other is 4 degrees. supplementary angles add to 180 degrees
It works out that the other two angles are 29 degrees and 52 degrees. Check: 29+52+99 = 180 degrees
58, complementary means the angles add to 90 degrees
They measure 105 degrees each.
64 degrees because the total of the angles has to equal 360 degrees for it to be a hexagon.
55 degrees
Its other 3 angles are 37 degrees, 143 degrees and 143 degrees
The other three angles will each measure 120 degrees.
If the rhombus has two angles of 112 degrees - then the other two angles must total 136 degrees.
All acute angles measure 50 degrees. All obtuse angles are supplementary to the acute angles, so they measure 130 degrees.
Each other of the alternate angles will measure 75 degrees because there are 180 degrees on a straight line.
the other is 4 degrees. supplementary angles add to 180 degrees
23 degrees and 67 degrees
It works out that the other two angles are 29 degrees and 52 degrees. Check: 29+52+99 = 180 degrees
Total interior angles ((2 x 7) - 4) right angles ie 900 degrees. Given angles total 570 degrees so each of the other angles is (900 - 570)/2 ie 165 degrees.
