D. Obtuse angle
and heres how I got it
An obtuse angle is 130 degrees. Any angle more than 90 degrees is obtuse, any angle under 90 degrees is acute, and 90 degrees is a right angle<span>.</span>
This would be the correct answer
Answer:
(c)Rhombus
Step-by-step explanation:
A parallelogram is a quadrilateral (has four sides) in which opposite sides are parallel to each other. Also for a parallelogram, the opposite sides and angles are equal to each other.
A rhombus is a parallelogram (that is opposites sides and angles are equal to each other and parallel) with all sides of equal length. The diagonals of a rhombus bisect each other at 90° to form four equal right angled triangles with the sides of the rhombus as the hypotenuse.
It is an infinite solution. It is this because if you subtract 12x on both sides, you get 8=8, causing an infinite solution equation.
