Question 311 Mark
The supplement of an obtuse angle is always _________ angle.
Answer
View full question & answer→The supplement of an obtuse angle is always $90^\circ$ angle.Solution:
Two angles are said to be complementary angles, if their sum is $90^\circ $.
Hence, if two angles are complementary, then each angle cannot be more than $90^\circ .$
Two angles are said to be complementary angles, if their sum is $90^\circ $.
Hence, if two angles are complementary, then each angle cannot be more than $90^\circ .$

Question 351 Mark
The supplement of an acute is always __________ angle.
Answer
View full question & answer→The supplement of an acute is always Obtuse angle. Solution: If angle is acute angle, then its supplement will be an obtuse angle. As, if we subtract an angle which is less than $90^\circ $ from $180^\circ $, then result will be an angle greater than $90^\circ .$

The supplement of a right angle is always _________ angle.
Answer
View full question & answer→The supplement of a right angle is always Right angle.
Solution: Let $x$ be the supplement of the right angle.
Then, $x + 90^\circ = 180^\circ $
$\Rightarrow x = 180^\circ - 90^\circ = 90^\circ $
Solution: Let $x$ be the supplement of the right angle.
Then, $x + 90^\circ = 180^\circ $
$\Rightarrow x = 180^\circ - 90^\circ = 90^\circ $

Answer
View full question & answer→An angle is $45^\circ .$ Its complementary angle will be $45^\circ .$
Solution:
Let $x$ be the required angle.
Then, $x + 45^\circ = 90^\circ \Rightarrow x = 90^\circ - 45^\circ = 45^\circ $
Solution:
Let $x$ be the required angle.
Then, $x + 45^\circ = 90^\circ \Rightarrow x = 90^\circ - 45^\circ = 45^\circ $
