The sum of the angles is 180 deg
2 + 4 + 9 = 15
2/15 * 180 = 24
4/15 * 180 = 48
9/15 * 180 = 108
The angles are 24, 48 and 108 deg
It is called a 30-60-90 triangle and it is a right triangle whose sides are always in the ratio:1:2:Square root (3).
An equilateral triangle, which has 3 angles of 60o.
Supplementary angles are 2 angles whose measures = 180o.
supplementaryA:Two angles whose sum measures a right angle are complementary angles.
Two angles whose measures add to 90 are complementary angles. An example is 45 and 45.
No. If the angles are in the ratio 3:4:5, the sides will be in the ratio sin(3):sin(4):sin(5) - NOT in the ratio 3:4:5.
