Answer:

a) 540°

b) 720°

c) 900°

d) 1440°

Step-by-step explanation:

The total measure of internal angles of a convex polygon is given by the formula ...

sum of angles = 180°(n -2) . . . . for an n-sided polygon

So, you count the sides, subtract 2, and multiply that result by 180°.

a) 180°(5 -2) = 540°

b) 180°(6 -2) = 720°

c) 180°(7 -2) = 900°

d) 180°(10 -2) = 1440°
