Answer:
-10y
Step-by-step explanation:
Hello,

=70 (sum of angles of a triangle=180°)

supplementary angles

translation BC

image of the angle DAB by the axis symmetry DB

opposed angles of a parallelogram
are supplementary.

opposed angles by the vertex

alterne-interne angles (sorry for the words English is difficult for me)
By definition, a parallelogram is merely a quadrilateral. Its key characteristics are having two sets of parallel sides. Consequently, it would have two sets of equal lengths, denoted as a and b. A perpendicular bisector is the red line in the picture that bisects length b into two lengths while creating a right angle. The area of a parallelogram is
A = bh, where
b is the side that meets with h
h is the perpendicular height of the parallelogram
Since h is not known, we have to solve it first through applying the pythagorean theorem.
h = √29^2 - 12^2 = 26.4 m
Thus,
A = (12 cm + 33 cm)(26.4 cm)
A = 1,188 square centimeters
8/12, 6/19 and 9/10!
All of them cannot be simplified.
but the rest can like
4/26 can be simplified by 2
and 10.22 can be simplified by 2
