90 - 20 = 70 degrees.
If it is a triangle then the 3rd angle is 70 degrees
70 degrees A right triangle has one angle that HAS to be 90 degrees. If the other is 20 degrees, and all three angles need to add to 180 degrees: 90+20+x=180 x=70
Let's denote the measure of the angle as x degrees. The complementary angle would then be 90 - x degrees. According to the given information, we have the equation x = 14(90 - x). Solving this equation, we find x = 70 degrees and the complementary angle is 20 degrees.
It is a right angle triangle and the 3rd angle would measure 70 degrees
Complementary angles add to 90 degrees so the complementary angle to 70 degrees has a measure of 20 deg.
110 degrees
55 degrees
35 degrees
Supplementary angles are two angles that measure up to 180 degrees. EXAMPLE: If the an angle measures 70 degrees, to find the missing angle, you subtract 70 from 180 because supplementary angles equal 180 degrees. Your answer (in this case 110) is the answer for the measure of the missing angle.
Since there are 180 degrees in a triangle, the measure of the 3rd angle would be 180 - 2(70) = 40 degrees.
90 - 20 = 70 degrees.
If it's an isosceles triangle and the apex angle is 70 degrees then the base angles will each measure 55 degrees
A pair of supplementary angles add up to 180 degrees. In this instance, the supplement of an angle of 70 degrees is 180 - 70 = 110 degrees.
