Answer:
x = 10°; angles are 50°, 46°, 84° (CW from left)
Step-by-step explanation:
The sum of the three angles is 180°, so ...
(6x +10°) +(4x +6°) +(7x +14°) = 180°
17x +10° = 180°
17x = 170°
x = 10°
__
Then the angles are ...
6x -10° = 6·10° -10° = 50°
4x +6° - 4·10° +6° = 46°
7x +14° = 7·10° +14° = 84°
T=number of hours she tutors.
r=number of hours she works a receptionist.
Tori is only able to work up to 20 hours per week.
t+r≤20
She tutors for $30 per hour and works as a receptionist for $10 per hour. She must earn at least $200 per week.
30t+10r≥200
Answer: t+r less than or equal to 20; 30t+10r greater than or queal to 200.
t+r≤20
30t+10r≥200
There are pi radians in 180 degrees. Therefore to convert degrees to radians we need to divide by 180 and multiply by pi, as follows:
Answer: i would say 280.
Step-by-step explanation: because if you add 180 plus another set of it it would make 280
