1

A right angle measures:

91% Answer Correctly

180°

90°

360°

45°
Solution

A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.

2

For this diagram, the Pythagorean theorem states that b2 = ?

47% Answer Correctly

c2 + a2

c2 - a2

c - a

a2 - c2

Solution

The Pythagorean theorem defines the relationship between the side lengths of a right triangle. The length of the hypotenuse squared (c2) is equal to the sum of the two perpendicular sides squared (a2 + b2): c2 = a2 + b2 or, solved for c, \(c = \sqrt{a + b}\)

3

What is 7a7 - 9a7?

74% Answer Correctly
63a7
-2a7
63a14
16
Solution

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

7a7 - 9a7 = -2a7

4

If a = c = 9, b = d = 6, and the blue angle = 75°, what is the area of this parallelogram?

66% Answer Correctly
24
27
36
54
Solution

The area of a parallelogram is equal to its length x width:

a = l x w
a = a x b
a = 9 x 6
a = 54

5

If BD = 17 and AD = 27, AB = ?

76% Answer Correctly
19
4
10
6
Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 27 - 17
AB = 10
