Each question on a test was worth 5 points. What was the total number of points if there were n questions?

1 answer:

8 0

The total number of points would be equal to 5n.

You would simply multiply 5 by the amount of questions. In this case, we do not know the amount, so we can use the variable n.

Sin 45° = opposite side / hypotenuse

1/2 = 8/h
h = 16

2)6/12 = 1/2
1/2 = sin 45°

6√3/12 = √3/2
√3/2 = cos 30°

Sum of angles of triangle = 180°
The 3rd angle = 180 - (45 + 30) = 180 - 75 = 105°

Angles = 30° , 45° , 105°
