Identify the following pair of angles as supplementary, complementary:
i. 35° & 145° ii. 40° & 50° iii. 15° & 75° iv. 112° & 68°
Point (0, -7) lies
(A) on the X-axis (B) in the second quadrant (C) on the Y-axis (D) in the fourth quadrant
If a^2 + b^2 + c^2 = 0, then a + b + c is equal to
(A) 0 (B) abc (C) 3abc (D) 2abc
Assertion (A): Zero is a rational number. Reason (R): Zero can be expressed as p/q, where p
and q are integers and q≠0.
(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of
the Assertion (A).
(B) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation
of the Assertion (A).
(C) Assertion (A) is true, but Reason (R) is false.
