Step-by-step explanation:

We have been given an image. We are asked to match each picture with its correct label.

A. Straight angle:

We know that straight is an angle equal to 180 degrees. We can see that 1st picture is a straight angle.

B. Minor arc:

We know that an arc is known as minor arc, when its measure is less than 180 degree. We can see that xy is minor arc represented by red color.

C. Inscribed angle:

We know that an inscribed angle is formed by two secants having a common endpoint. Angle XYZ in 3rd picture is an inscribed angle.

D. Chord:

We know that a chord is a line segment, whose both endpoints lie on the circle, therefore, 4th picture represents chord of circle.

E. Secant:

We know that a chord is a line, whose both endpoints intersects circle at least at two points, therefore, 5th picture represents secant of circle.

F. Complementary angles:

We know that when two angles add up-to 90 degrees, they are complementary to each other. Therefore, the 5th picture represents complementary angles.

G. Acute angle:

We know that an angle is known as acute angle, when its measure is less than 90 degree. Therefore, the 6th picture represents an acute angle.

H. Intersecting lines:

We know that when two lines share exactly one point, they are know as intersecting lines. Therefore, the 7th picture represents intersecting lines.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
