Answer:
- Q3. 12 units
- Q4. 6.33 units
- Q5. 66.19°
Step-by-step explanation:
Q3
DE and DF are legs and EF is hypotenuse
- DE = √EF² - DF²
- DE = √13² - 5² = √169 - 25 = √ 144 = 12
- DE = 12 units
Q4
PR is opposite side of angle Q and RQ is adjacent side
- tan 54 = PR/RQ
- tan 54 = PR / 4.6
- PR = 4.6tan 54
- PR = 6.33 units
Q5
As previous question, using tan as BC is opposite and AC is adjacent leg of angle A
- tan A = 6.8/3
- tan A = 2.266
- A = arctan (2.266)
- A = 66.19°
Answer:
The unit of measure used in the study is "inches"

has y = 0 as a solution.
Selection B is appropriate.
Answer:

Step-by-step explanation:
So we have the equation:

First, subtract 9 from both sides:

Divide both sides by -4:

Definition of Absolute Value:

Subtract 3 from both sides:

Divide both sides by 5:

And we're done!
