Answer:
AC = 3.72 units
Angles:
A = 132.6°
C = 27.4°
Step-by-step explanation:
AC² = 5² + 8² - 2(5)(8)cos(20)
AC² = 13.82459034
AC = 3.718143399
3.718143399/sin20 = 8/sinA
sinA = 0.7358944647
A = 180 - 47.38285134
A = 132.6171487
3.718143399/sin20 = 5/sinC
sinC = 0.4599340405
C = 27.38285134

Answer:
![2.75\%](https://tex.z-dn.net/?f=2.75%5C%25)
Step-by-step explanation:
To find what percentage a certain value is of another value, simply divide the first value by the second, respectively.
We want to find want percentage that 7,562.5 is of 275,000. Therefore, we will divide 7,562.5 by 275,000 to obtain a decimal:
![\frac{7,562.5}{275,000}=0.0275](https://tex.z-dn.net/?f=%5Cfrac%7B7%2C562.5%7D%7B275%2C000%7D%3D0.0275)
To convert from a decimal to a percentage, multiply by 100:
![0.0275 \cdot 100=\boxed{2.75\%}](https://tex.z-dn.net/?f=0.0275%20%5Ccdot%20100%3D%5Cboxed%7B2.75%5C%25%7D)
Answer:
D) infinitely many solutions
Step-by-step explanation:
5 ( x-3 ) - 3x = 8x - 15 - 6x
5x - 3x - 15 = 8x - 6x - 15
2x - 15 = 2x - 15
2x = 2x
Since, equations of both lines are same. Therefore, there are infinitely many solutions.
