We will use B for the number of baseball cards and H for the number of hockey cards.
B = 5H
B + H = 840
Use substitution by plugging 5H in for B in the second equation.
5H + H = 840
6H = 840
H = 140
If there are 140 hockey cards, then there are 5*140 = 700 baseball cards.
So the answer is 700.

The Triangle Sum Theorem states that the sum of the angles of a triangle equal 180°.
Therefore,
45° + 62° + k = 180
107° + k = 180
k = 73°
The value of k is 73°
