In a triangle ABC B is equal to 45 degrees C is equal to 34 degrees determine the magnitude of the angle A
| January 25, 2021 | education
B = 450
C = 34
A =?
If we consider that the sum of all angles in any triangle is 180, then it turns out that from 180 you need to subtract the sum of 2 known angles.
Therefore, we get the following example:
180 – (45 + 34)
45 + 34 = 79 – angles B and C.
180 – 79 = 101 – angle A.
Answer: A = 101.
