In the figure below, what is the relationship between ACD and DCB

They are congruent angles
They are supplementary angles
They are vertical angles
They are complementary angles

The figure below is a rhombus with one diagonal drawn in. Find the length of the side labeled x.

x=8

x=7

x=11.4

x=9

Using the figure below, find the measure of

90 Degrees

31 Degrees

122 Degrees

62 Degrees

Problem 1

Explanation:

The two angles combine to form a straight angle (which is 180 degrees). Another term for these angles is "linear pair" since they form a straight line.

Problem 2

Explanation:

The diagonal is never used in this problem. For any rhombus, the four exterior sides are always the same length.

Problem 3

Explanation:

We use the angle addition postulate. This allows us to combine angles BAC and CAD to form angle BAD.

(angle BAC)+(angle CAD) = angle BAD

30 + x = 92

x = 92-30

x = 62

angle CAD = 62

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
