Manipulate the triangle so angle A measures 41° and
angle C measures 49º.
What is the approximate measure of angle B?
Angle B = (41, 90, 49, 80)
What is the sum of the interior angles of the triangle?
(90, 170, 180, 200)

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
