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°
Answer:
Step-by-step explanation:
By Geometric mean property:
The answer would 12. Think of ratios as fractions. 1/2 = 6/12 So, 6:12
5:11 is the ratio of those who completed in the freestyle to those who didn't. It <u>would not be 5:16 </u>because 5 of the members from the 16 members did the freestyle. 16-5 equals 11. 5(Men who did freestyle):11(Men who didn't do freestyle)
Your answer is 5:11.
The answer is D because Sine and cosine equals 90.
