Find the measure of the acute angle in a rhombus if its side makes with the diagonals angles such that one of them is three times larger than the other.

Explanation:

A rhombus has 4 angles. Two obtuse that are equal and two acute that are equal. If all of the angles in a rhombus add up to 360°, then one acute and one obtuse must add up to half that: 180°.

The acute to obtuse angle ratio is 1:3. Think of this as four parts. One part acute, three parts obtuse.

180 ÷ 4 = 45

Therefore, The acute angle is 45°, and the obtuse angle is 135°

authors choose a genre based on their purpose. fiction works well for teaching a lesson, as in fables. however, presenting facts and opinions in nonfiction might be a better way to present information. when authors begin to write, they think about what they want the reader to understand or experience. while fiction may be the best genre for storytelling, nonfiction may be the most clear for sharing facts, so both genres have merits.
