(e) When the sum of the measures of two angles is that of a straight angle and if one of them is acute then the other should be ___.

Solution:

We will use the concept of angles to solve this.

(a) An angle whose measure is less than that of a right angle is acute.
(b) An angle whose measure is greater than that of a right angle is obtuse.
(c) An angle whose measure is the sum of the measures of two right angles is straight.
(d) When the sum of the measures of two angles is that of a right angle, then each one of them is acute.
(e) When the sum of the measures of two angles is that of a straight angle, and if one of them is acute, then the other should be obtuse.
