Answer:

128 degrees, so C is again the answer.

Step-by-step explanation:

Since angles 3 and 11 are corresponding(from your previous question), angles 1 and 11 will add up to 180 degrees, since a line is that long. Therefore your answer is 180-(degrees of angle 1)= 180-52= 128

m∠11 = 128°.

A line that cuts three parallel lines forms congruent angles which means they measure the same.

In this problem m∠1 = 52° = m∠4 = m∠5 = m∠8 = m∠9 = m∠12, and m∠2 = m∠3 = m∠6 = m∠7 = m∠10 = m∠11.

To calculate m∠11, we know that m∠12 = m∠1 = 52°, the sum of the angle of m∠11 and m∠12 is 180°. Then:

m∠11 + m∠12 = 180°, with m∠1 = 52° = m∠12

m∠11 + 52° = 180°

m∠11 = 180° - 52°

m∠11 = 128°

Which best describes the centroid of a triangle?

aivan3 [116]

Answer:

Option: B is the correct option:

B. The point where the three medians of the triangle intersect

Step-by-step explanation:

We know that the centroid of a triangle is the point where the three medians of the triangle intersect.

The centroid of a triangle is also known as the center of gravity of the triangle.

The median of a triangle is a line segment that is drawn form a vertex of a triangle such that it meets the opposite site of the triangle at the mid-point.
