Answer:
2,4,6 and 8 are all 40degrees that means 1,3,5 and 7 are 140 degrees. 2,4,6, and 8 are at a diagonal that allows them to equal eachother. because 2 is given 40degrees as the angle 4,6 and 8 must also be 40 degrees. a flat line is 180 degrees. 180-40=140
you have vertical angles alternate interior, alternate exterior
Step-by-step explanation:
Vertical Angles: a pair of opposite congruent non-adjacent angles formed by intersecting lines; share a vertex
Alternate Interior: when a transversal intersects two lines, alternate interior angles are on opposite sides of the transversal and on the inside of the given lines
Alternate Exterior: when a transversal intersects two lines, alternate exterior angles are on opposite sides of the transversal and on the outside of the given lines They are congruent.
Answer:
Well in set A, all of the sides are the same length but they are different shapes.
In set B, all of the angles are the same, they are just differnet shapes.
Hope this helps! :)
2πr^2 + 2πrh.
r is the radius circle face.
h is the length/height of the cylinder.
πr^2 is the formula for circles, and there are 2 circles in a cylinder. So 2 x πr^2 would be determine the area of the 2 circles.
2πr is the formula for circumference. 2πr x h would the area of the curved face.

If the exterior angle of the bases is 150°, then the measure of the angle of each base is
30° and the measure of the vertex is 120°. If the exterior angle of the vertex is 150°, then the measure of the angle of each base is
75° and the measure of the vertex is 30°.</span>
