Problem #3 The diagram shows an obtuse triangle
ABC with AB = 57 cm, AC = 48 cm and
BÂC=117 degrees
Calculate:
a the length BC
(3 marks)
b the area of triangle ABC (2 marks)
c the size of the angle ABC. (3 marks)

Find the number of positive three-digit even integers whose digits are among 9, 8, 7,5, 3, and 1.

Which of the following is a correct equation based on the triangle shown?

The dot plot below shows the number of toys 21 shops sold in an hour: dot plot labeled number of toys sold shows 6 dots over 0, 4 dots over 1, 3 dots over 2, 3 dots over 3, 2 dot over 4 and 3 dots over 9 is the median or the mean a better center for this data and why? median; because the data is not symmetric and there are outliers median; because the data is symmetric and there are no outliers mean; because the data is symmetric and there are no outliers mean; because the data is skewed and there are outliers
