Answer:
She payed $34.60.
Step-by-step explanation:
It cost $19.60, just to rent the bike.
Then multiply $6 × 2 (hours) = 12
Now 6 ÷ 2 = 3 (half hour)
Add 12 + 3 = 15
Add everything together
19.60 + 15
You then get $34.60.
Those are adjacent angles. They equal 180 degrees.
10x-20+6x+8= 180
16x-12=180
Add 12.
16x= 192
x=12
I hope this helps!

Step-by-step explanation:
Because you are adding to it so it would be a positive
Answer:
15° , 45°, 120°
Step-by-step explanation:
sum the parts of the ratio, 1 + 3 + 8 = 12 parts
the sum of the 3 angles in a triangle = 180° , then
180° ÷ 12 = 15° ← value of 1 part of the ratio, then
3 parts = 3 × 15° = 45°
8 parts = 8 × 15° = 120°
the 3 angles are 15° , 45° , 120°
