Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos C = (25² + 27² - 28²)/(2*25*27)
- cos C = 0.4222
- m∠C = arccos 0.4222
- m∠C = 65°

(1488-80)/2+80= adult tickets
Answer:
All lines, with a value for the slope, will have one zero.
Step-by-step explanation:
To find the zero of a linear function, simply find the point where the line crosses the x-axis. Zeros of linear functions: The blue line, y=12x+2 y = 1 2 x + 2 , has a zero at (−4,0) ; the red line, y=−x+5 y = − x + 5 , has a zero at (5,0) .
