What type of polygon is shown?

convex heptagon
concave heptagon
concave octagon
convex octagon

(B)

step by step explanation:

Convex Octagon: A convex octagon has no angles pointing inwards. Also, no internal angles can be more than 180°.

Concave Octagon: When any internal angle is greater than 180° it is concave.

Convex heptagon: A convex heptagon is a seven-sided polygon in which we can connect any two of its vertices with a line segment.

Concave heptagon: If any internal angle is greater than 180° then the polygon is concave.

Now, in the given figure, it can be seen that the number of the sides are seven and also one angle is greater than 180° , thus the given figure is concave heptagon.

Hence, option B is correct.

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3
