2.50 would be 25% out of 100%
Answer:
Angle 2 = 105
Step-by-step explanation:
Since these angles are cut by a transversal the angle from above is congruent to angle #2. You can say the theorem that is used to make these two congruent is the Alternate exterior angles theorem which states this.
Hope this helped!
B^2 - 4ac
(-9)^2 - 4 (2)(9)
= 81 - 72
=9 >0 yet it is a perfect square (3^2 =9)
So , it is 2 real and rational roots
(x-3) ( 2x-3) =0
x = 3 , x = 3/2
Answer:
AC = 40
Step-by-step explanation:
A quadrilateral is a polygon shape with four sides and four angles. The interior angle of a quadrilateral sums up to 360°.
A parallelogram is a quadrilateral (has four sides and four angles) in which has two pair of opposite sides are parallel to each other. The diagonals of a parallelogram bisect each other.
Given parallelogram ABCD:
Diagonals AC and BD bisect each other at point E. Hence:
AC = AE + CE (line segment addition postulate)
Also:
AE = CE (diagonal BD bisects AC at point E).
Hence; x + 16 = 5x
5x - x = 16
4x = 16
x = 4
AE = x + 16 = 4 + 16 = 20; CE= 5x = 5(4) = 20
AC = AE + CE = 20+ 20 = 40
