The measures of two angles of a triangle are given find the measure of the third angle 47 and 62
the answer is 22,97
two-thirds of an angle is 30degree more than its supplemant. find the angle
Remember the sum of the 3 angles of a triangle = 180degrees Let angle 1 = x angle 2 = 2x angle 3 = x-20 Sum = x + 2x + x - 20 =180o 4x - 20 = 180o 4x = 200o x = 50o 2x = 100 o x - 20 = 30o angle 1 = 50o angle 2 = 100 o angle 3 = 30o
more than a 90 degree angle but less than a 180 degree angle
