Find the angles of a triangle if one of them is 75 ° and the difference between the other two is 45 °.
| September 18, 2021 | education
The angles in a triangle add up to 180 °. If we know 1 angle, then, therefore, we can calculate the sum of the other two angles:
180 – 75 = 105 °.
Thus, one corner of the triangle will be equal to 30 °. And the 3rd angle will be:
30 + 45 = 75 °.
Answer: 1 angle = 75 °, 2 angles – 75 °, 3 angles – 30 °.
