You can calculate the angle
Let X =angle in degrees
The complement is 90 -x
1/3(90-X) = X
30 - X/3 = X
30 = 4X/3
X = 22.5 degrees
55°
A right angle is one of 90 degrees. An acute angle of 30 degrees would be one third of that.
The third angle is (128 degrees) minus (the second angle).
The third angle measures 18 degrees.
45
63 degrees because 180 -39 -78 = 63
45 degrees.
The third angle is 34.5 degrees
It is one part of an angle that has been divided into three equal parts. It can have any measure.
If it is a triangle then the 3rd angle is 70 degrees
Let the measure of the first angle be x⁰. So that the second angle would be (x + 21)⁰, and the third one would be (x - 15)⁰.Since the sum of angle measures in a triangle is 180⁰ we have:x + x + 21 + x - 15 = 1803x = 174x = 58Thus, the first angle is 58⁰, the second angle is 79⁰, and the third angle is 43⁰.
45 degrees
