Recast the problem by creating a right-angle triangle with the missing slope forming the hypotenuse. Determine the length of the base of this triangle by subtracting the measure of the lesser parallel side from the length of the longer parallel side. ...
Because the sum of two complementary angles is 90 degrees, if you're given the measurement of one angle x, the measurement of its complementary angle is 90 - x degrees. So if you're told that an angle measures 30 degrees and asked to find its complement, you could calcul...
isosceles triangle, is formed when the third, non-base angle is a right angle. The height, or altitude, of the triangle is the perpendicular distance from the base to the top vertex. To find an unknown side of a triangle, you must know the length of other two sides and/or the ...
