Hurry a sundial has circular dial and a right triangle shaped piece, called a gnomon. one of the angles of the gnomon is 52°what is the measure of the smallest angle of the gnomon? a.38 b.90 c.142 d.218

The three inside angles of a triangle need to equal 180 degrees.

In a right triangle one of the angles is 90 degrees.

This means the other two angles need to equal 180-90 90 degrees.

You are given one of the angles of 52 degrees, so subtract that from 90 to find the third angle.

90 - 52 = 38 degrees.

The answer is A.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
