DIRECTION : In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
Assertion : An angle is 140 more than its complementary angle, then angle is 520.
Reason : Two angles are said to be supplementary if their sum of measure of angles is 1800.
  • a)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.
Correct answer is option 'A'. Can you explain this answer?

DIRECTION : In the following questions, a statement of assertion (A) i...
We know that two angles are said to be supplementary if their sum of measure of angles is 1800.
So, Reason is correct.
Let the angle be x . Complement of x = (900 - x)
Since, the difference is 140, we have x – (900 – x) = 140
⇒ 2x = 1040
⇒ x = 520
So, Assertion is also correct
But reason (R) is not the correct explanation of assertion (A).
Correct option is (b) Both assertion (A) and reason (R) are true and reason (R) is not the correct explanation of assertion (A).

DIRECTION : In the following questions, a statement of assertion (A) i...
Assertion: An angle is 140 more than its complementary angle, then angle is 520.
Reason: Two angles are said to be supplementary if their sum of measure of angles is 1800.

Explanation:
To understand the given assertion and reason, let's first define what complementary and supplementary angles are:

Complementary angles: Two angles are called complementary angles if the sum of their measures is 90 degrees.

Supplementary angles: Two angles are called supplementary angles if the sum of their measures is 180 degrees.

Now let's analyze the given assertion and reason:

Assertion: An angle is 140 more than its complementary angle, then angle is 520.
This means that if we have an angle x, its complementary angle would be (90 - x), and according to the assertion, x = (90 - x) + 140.

Reason: Two angles are said to be supplementary if their sum of measure of angles is 1800.
The reason states that two angles are supplementary if their sum is 180 degrees.

Now let's evaluate the given assertion and reason:

If an angle is 140 more than its complementary angle, it means that the measure of the angle is (90 - x) + 140 = 230 - x.
According to the assertion, this measure is equal to 520. So we have the equation 230 - x = 520.

Solving this equation, we get x = -290, which is not a valid angle measure.

Therefore, the assertion is false.

However, the reason is true. Two angles are indeed supplementary if their sum is 180 degrees.

Hence, the correct answer is option c) Assertion (A) is true but reason (R) is false.
