I will assume that this is referring to a triangle.
The angles of a triangle add up to 180 degrees.
Let the missing angle = a
then a + 22 degrees + 51 degrees = 180 degrees
a = 107 degrees
If it is a complementary angle, the missing angle is 52 degrees. If it is a supplementary angle, the missing angle is 142 degrees. If it is an opposite angle, the missing angle is 38 degrees. Obviously, you need to know what type of angle you're looking for.
The sum of the internal angles of a triangle is 180 degrees. Since you know this is a right-angled triangle, you know that one side is 90 degrees. If the other angle is 28 degrees, then you know that the remaining angle must be 180 - 90 - 28 = 62 degrees.
30 degrees
Supplementary means they add to 180 degrees. If one is 102, then the other is 180 - 102 = 78 degrees.
It depends on what your measuring and the measure of the other given angles. "X" is also known as the missing angle. ex. In triangle ABC, the measure of angle A is 40 and the measure of angle B is 80 find the missing angle. answer- Angle C would be 60 because a triangle's angles add up to 180 degrees.
If it is a complementary angle, the missing angle is 52 degrees. If it is a supplementary angle, the missing angle is 142 degrees. If it is an opposite angle, the missing angle is 38 degrees. Obviously, you need to know what type of angle you're looking for.
Thmissing angle is 83
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.
If it's a right angle triangle then the the third angle is 60 degrees.
If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.
Fifty degrees. 90+40+90=180
The angle opposite the 55 degree angle will also be 55 degrees. The other two angles will each measure 180 - 55 = 125 degrees.
The angles must add up to 180o Let the missing angle be x so, x + 62o + 47o = 180o x = 71o
False because the 3rd angle has to be a right angle of 90 degrees because the 3 angles of any triangle add up to 180 degrees.
A corner of 90 degrees is a right angle
No angle can be complementary to a 140 degree angle, as the sum of complementary angles is 90 degrees. But angles which are supplementary to each other add together to form a 180 degree angle.
45 and 90 degree angles
