Answer:
-11/10 or -1.1
Step-by-step explanation:
To start, let's get rid of those pesky decimals by multiplying everything by 2. Then we get 9 + 20r = -13. Now, let's isolate the r by subtracting 9 from both sides to get 20r = -22. Finally, we need to divide everything by 20 to get r = -11/10 or -1.1.
Answer: b
Step-by-step explanation:
The answer is the third option 78 degrees
First part is 1:2 because there is 1 hour to every 2 shows. Second part is 3:6 shows because 3 hours is 6 shows. Hope this helps, please rate brainiest answer!
Answer:

Step-by-step explanation:
If angle C is the right angle, then side c is the hypotenuse.
Use Pythagoras' Theorem
to find the length of side a:
Given:





<u>Tan Trig Ratio</u>

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
Given:
= A- O = side opposite angle A = a = 9
- A = side adjacent angle A = b = 2√22
