Question 3

Two angles of a triangle measure 52° and 68°. What is the third angle?

Accepted Answer

60°

Answer

The angles in a triangle sum to 180°. 52 + 68 = 120, and 180 − 120 = 60°.

Question 4

A circle has a radius of 5 cm. Using π ≈ 3.14, what is its approximate circumference?

Accepted Answer

31.4 cm

Answer

Circumference = 2πr = 2 × 3.14 × 5 = 31.4 cm. 78.5 cm is the area.

Question 5
