If one angle of an isosceles triangle is 68", then possible values of the second angle are?
- Any value between 68° and 180
- Any value between 1
- Any value between 68° and 112°
- 44° or 56°
Explanation
If one angle of an isosceles triangle is 68°, then:
- If 68° is the vertex angle, the other two equal angles = (180 - 68) / 2 = 56°
- If 68° is one of the equal base angles, then the vertex angle = 180 - 2×68 = 44°
So, possible values for the second angle are 44° or 56°
