The measures of the angles of a triangle are in the ratio 4 : 5 : 9. The triangle is:
1 An acute angled triangle
2 A right angled triangle
3 An obtuse angled triangle
4 None of the above
Explanation:
A right angled triangle let the angles be 4x, 5x and 9x 4x + 5x + 9x = 180\(^{1}\) 18x = 180\(^{1}\) x = 10\(^{1}\) So the angles are 4 × 10\(^{1}\) = 40\(^{1}\) 5 × 10° = 50° 9 × 10° = 90 One of the angle is 90\(^{1}\), so the triangle is right angled triangle.

If two angles in a triangle are 40° and 60°, then the third angle is:
1 90°
2 80°
3 70°
4 60°
Explanation:
80° Let the third angle be x Sum of angles = 180° 40° + 60° + x = 180° 100° + x = 180° x = 80°

The sides of a triangle have lengths (in cm) 10, 6.5 and a, where a is a whole number. The minimum value that a can take is:
1 6
2 5
3 3
4 4
Explanation:
4 As we know, sum of any two sides in a triangle is always greater than the third side. So, only 4 is the minimum value that satisfies as a side in triangle. \(\begin{cases}10<6.5+4\\6.5<10+4\\4<10+6.5\end{cases}\Bigg\}\)
