1 x = 50
2 x = 100
3 x = 60
4 x = 80
Explanation:
x = 80 In the figure, AOB is a straight line \(\angle\text{AOC}+\angle\text{COD}+\angle\text{DOB}=180^\circ\) \(\Rightarrow55^\circ+\text{x }+45^\circ=180^\circ\) \(\Rightarrow\text{x}+100^\circ=180^\circ\) \(\Rightarrow\text{x}=180^\circ-100^\circ=80^\circ\)

Mark \((\checkmark)\) against the correct answer. An angle is 32° less than its supplement. The measure of the angle is:
1 37°
2 74°
3 148°
4 None of these.
Explanation:
74° Let required angle = x Then its supplement angle = x + 32 But x + x + 32° = 180° 2x = 180° - 32 = 148° x = 74° Required angle = 74°

2 \(3\sqrt{2}\text{cm}\)
3 \(4\sqrt{2}\text{cm}\)
