Answer» A rhombus has 2 congruent opposite acute angles and TWO congruent opposite OBTUSE angles. One of the properties of a rhombus is that any two internal consecutive angles are supplementary. Let x be the acute angle. The obtuse angle is twice: 2x. Which gives the FOLLOWING equation. x + 2 x = 180 degrees. Solve the above equation for x. 3x = 180 degrees. x = 60 degrees. We use formula 2 for the area of a rhombus knowing the side length and one of the angles. area of rhombus = (10 feet) 2 SIN (60 degrees) = 86.6 feet 2 (rounded to 1 decimal PLACE) [Updated by Reviwer] |
