An isosceles triangle contains three angles that measure 40°, x°, and y°. Which of the following CANNOT be true?
1 x = y
2 x = 50
3 x - y = 60
4 x = 70
5 x = 100
Explanation:
x = 50 Every triangle has three angles that add up to 180°, and an isosceles triangle has two equivalent angles. Therefore, the three angles of this triangle are either 40° + 40° + 100° or 40° + 70° + 70°. In any case, this triangle include a 50° angle. Hence, x = 50

The difference between two angles is 19° and their sum is \(\frac{890^\circ}{9}\) Find the greater angle.
1 63°
2 35°
3 27°
4 59°
Explanation:
59° Let the two angles be a and b Then, a - b = 19 and, \(\text{a}+\text{b}=\frac{890}{9}\) Adding the two equations, \(\text{2a}=\frac{890 +19\times9}{9}\) \(\text{2a}=\frac{1061}{9}\) Thus, \(\text{a}=\frac{1061}{18}\) \(\text{a}\approx59^\circ\)

The \(\triangle\) formed by BC = AC = 7.2 cm and \(\angle\text{C} = 90^\circ\) is:
1 a right angled\(\triangle\)
2 an isosceles\(\triangle\)
3 a right angled isosceles \(\triangle\)
4 no \(\triangle\) is formed
Explanation:
a right angled isosceles \(\triangle\) \(\because \text{BC} = \text{AC}\) it is isosceles. \(\because \angle\text{C} = 90^\circ\) it is right angled. So, \(\triangle\text{ABC}\) is right angled isosceles \(\triangle\)
