48 degrees. The complementary angle measure is 90 degrees minus the angle you are given.
The sum of the angles in a triangle equals 180, so the third angle is forty degrees. JTPaulson
That's a little less than half of a right angle (90 degrees).
43 because 43 + 47 = 50.
since it is a right triangle there is one 90 degree angle and another of the angles is 45 degrees. there is 180 degrees in a triangle so the missing angle is 45 degrees.
The third angle must be 90 degrees, so you have an "isosceles right triangle".
Since the sum of the internal angles of a plane triangle is 180 degrees, the measure of the missing angle is 65 degrees. 180 - 74 - 41 = 65 degrees.
The optimal angle to fire a projectile if the objective is distance is 45 degrees. It follows that the distance traveled decreases whether the angle is increased or decreased from 45.
9 equal sides
It is reflected 90 degrees from its original direction.
A 45-degree angle is an acute angle
The side adjacent to the forty degrees of a right triangle with a hypotenuse of 6 meters and one of its angles measuring forty degrees is: 4.6 meters.
