Answer:
You are looking for the arc sine of 55 degrees???
and then you will multiply it by 25 an divide it by 18???

Answer:
No
Step-by-step explanation:
To determine if the 3 sides form a right triangle.
Use the converse theorem of Pythagoras.
If the square of the longest side is equal to the sum of the squares of the other two sides then the triangle is right,
longest side = 14 and 14 ² = 196
9² + 12² = 81 + 144 = 225
Since 196 ≠ 225 the triangle is not right
The y-intercept of the graph shows that at m = 0, c = 15. We can see a constant slope that causes the graph to pass through m = 20, c = 20, as well as m = 40, c = 25. This shows a constant increase of $5/20 minutes, or a slope of 5/20 = 1/4. Based on slope-intercept form y = mx+b, the equation would be c = (1/4)m+15, from 0 <= m <= 44,640. This is the second of the given choices.
1/4 is equal to 2/8, and you only add the numerators in fractions, so the answer is 2/8 + 7/8 which is 9/8, or 1 1/8.
x+23+32+47=180
x+102=180
x=78
O. is the correct answer!!
