Problem Solving with Angles Quiz Level

Mathematics
1 answer:
Oksi-84 [34.3K]2 years ago
7 0

Answer: x= 63, y= 27

Step-by-step explanation:

x and angle measure 117 are a linear pair. They sum to 180.

117+x= 180. Subtract 117 from both sides.

x = 63

Looking at the relationship of x and y, the diagram shows that the two together equal 90 degrees. Add the two together and set equal to 90.

63+y= 90. Subtract 63 from both sides.

y = 27

| -6x - 3 | > 15

This expression can be written as:

a) -6x - 3 > 15 
b) -15 > - 6x - 3

Solving a part:

- 6x - 3 \ \textgreater \  15 \\  \\ 
- 6x \ \textgreater \  18 \\  \\ 
x \ \textless \  -3

Solving b part:

-15 \ \textgreater \  - 6x - 3 \\  \\ 
-12 \ \textgreater \  - 6x \\  \\ 
2 \ \textless \  x

or we can write:
x > 2

So the solution to given inequality is:
x \ \textless \  -3  \\ or  \\ x \ \textgreater \  2

The second option correctly lists this solution.
