If the first two add up to 45 degrees, then the third angle is 135 degrees.
If each of the first two is 45 degrees, then the third angle is 90 degrees.
55 degrees
90 degrees
Assuming you mean the third angle of a triangle... 64 degrees.
If the first two angles of a triangle are 45 degrees and 71 degrees then the 3rd angle is 64 degrees.
There are 180 degrees in a triangle. So: 3rd angle=180-38-97=45
90 degrees
The sum of the interior angles of a triangle add up to 180o. So 180 - (45 + 71) = 64o
In any triangle, all three inside angles always add up to 180 degrees.If two of the angles are 45 degrees each, then that takes care of 90 degrees altogether,and you have 90 degrees left for the third angle.
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
the other angle has to be 120 degrees, so that both angles add up to 180 degrees.
An angle that measures 55 degrees is classified as an acute angle, which means it is less than 90 degrees. In trigonometry, this angle would fall in the first quadrant. It is commonly found in geometric shapes such as a right triangle or a pentagon.
