In euclidean (plane) geometry, the sum of the interior angles of any triangle is 180 degrees. Add the two angles you know (right angles = 90 degrees) and subtract that sum from 180.
Without more information on the problem, that's the most I can assume
If that's a triangle, the third angle is 90 degrees.
Assuming the third angle is x... 180 = 15 +85 + x 180 = 100 +x 80 = x The third angle is 80 degrees
Use a protractor.
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.
the measure of the inscribed angle is______ its corresponding central angle
The third angle is [180-(32+70)] = 180-102 = 78
The third angle is 93 degrees
If two angles of a triangle each measure 55 what is the measure of the third angle?
55°
100.
Two angles of a triangle add up to 65°. What is the measure of the third angle?
The third angle is (128 degrees) minus (the second angle).
You find the arc measure and then you divide it in half to find the inscribed angle
If that's a triangle, the third angle is 90 degrees.
Use a protractor.
A right angle is one of 90 degrees. An acute angle of 30 degrees would be one third of that.
Assuming the third angle is x... 180 = 15 +85 + x 180 = 100 +x 80 = x The third angle is 80 degrees
