How is the latitude and longitude system different to the x and y coordinates on a graph?
On a graph, 'x' and 'y' are marked and measured in length or distance units. Latitude and longitude are marked and measured in angles.
Formula of N-sided polygons?
Sum of interior angles of an n-sided polygon = (n-2) x 180Sum of one interior angle of an n-sided polygon = (n-2) x 180 then divide by n.
What is the angle of a triangle measuring 68 X 68 X 82?
It is an isosceles triangle having 3 interior angles 2 of which are equal in size and the 3 angles add up to 180 degrees. Use Pythagoras' theorem to find its altitude and then use trigonometry to find the sizes of its angles. The angles work out as 53 degrees, 53 degrees and 74 degrees
What letter in the alphabet has 2 obtuse angles?
X and Y each have a pair of obtuse angles.
Find the measures of two complementary angles if the difference in their measures is 18?
If x and y are the two angles, then x + y = 90 and x - y = 18 Adding the two equations together gives 2x = 108 so that x = 54 and then y = x - 18 = 36
