A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.

A parallelogram has two pairs of opposite equal angles.
ABCD so
A = C and B = D
A = 2x + 35
C = 3x - 5
2x + 35 = 3x - 5
35 + 5 = 3x - 2x
40 = x
A = (2 x 40) + 35 = 115
A = C = 115
Sum of angles of a quadrilateral = 360
Angles B and D are equal
So
B = (360 - (115 + 115))/ 2
= 130/2
= 65
B = D = 65
