By drawing a sketch from the given information and then using trigonometry the height of the hill works out as 276 meters to the nearest whole meter.
They are called supplementary angles. See the related link below for more information.They are complementary angles that add up to 90 degrees
Angles are measured either in degrees or in radians.
Yes. Quadrantal angles have reference angles of either 0 degrees (e.g. 0 degrees and 180 degrees) or 90 degrees (e.g. 90 degrees and 270 degrees).
It can be either acute or obtuse. An acute angle is less than 90 degrees and all 3 angles add to 180 degrees. For example, If two angles are 60 degrees (acute) then the 3rd is 60 degrees (acute). If two angles are 30 degrees (acute) the 3rd is 120 degrees (obtuse).
The angles are 140 degrees, 20 degrees and 20 degrees that add up to 180 degrees
44 degrees
Adjacent angles are two angles that are next to each other and share one side (ray) in common. They do not have to add up to 180 degrees, but they can. If the two of them add up to 180 degrees, they are called a linear pair, since their non-common sides will be opposite rays that make a straight line. Two 90-degree angles that are adjacent are a linear pair. They are supplementary (meaning they add up to 180 degrees) and a sketch of them will look like a T, either upside-down (typical), sideways, or right-side up, depending on how you want to draw them.
It is either 90 degrees or 180 degrees.
Either two right angles, or one obtuse and one acute.
-- all four interior angles add up to 360 degrees-- any pair of adjacent angles adds up to 180 degrees-- the members of either pair of non-adjacent angles are equal
Yes. The sum of the internal angles of every quadrilateral is 360 degrees, so either all angles are 90 degrees or at least one must be.
A quadrilateral can only have either 2 right angles or four. As you may (or may not) know, the angles in a quadrilateral must add up to 360 degrees. If you have 3 right angles that adds up to 270 degrees, so the last side must also be 90 degrees.
