Question

Which of the following are true?
(i) 76° is an acute angle.
(ii) 180.43° is a reflex angle.
(iii) The complement of 13° is an acute angle.
(i) and (ii) only
(i) and (iii) only
(ii) and (iii) only
(i), (ii), and (iii)

Answer 1

An acute angle has measure less than 90 so (i) is true.
A reflex angle has measure more than 180° but less than 360° so (ii) is true.
Complementary angles sum to 90 so the complement of a 13 degree ange is 77 and therefore acute so (iii) is true.

Final Answer:--> (i), (ii), and (iii) are true
