Answer:
![Area = 337](https://tex.z-dn.net/?f=Area%20%3D%20337)
Step-by-step explanation:
Given
![a = 42.5](https://tex.z-dn.net/?f=a%20%3D%2042.5)
![c = 35.5](https://tex.z-dn.net/?f=c%20%3D%2035.5)
![B = 153.5^\circ](https://tex.z-dn.net/?f=B%20%3D%20153.5%5E%5Ccirc)
Required
Area of triangle
This is calculated as:
![Area = 0.5 *a* c * \sin(B)](https://tex.z-dn.net/?f=Area%20%3D%200.5%20%2Aa%2A%20c%20%2A%20%5Csin%28B%29)
This gives:
![Area = 0.5 *42.5* 35.5 * \sin(153.5)](https://tex.z-dn.net/?f=Area%20%3D%200.5%20%2A42.5%2A%2035.5%20%2A%20%5Csin%28153.5%29)
![Area = 0.5 *42.5* 35.5 * 0.4462](https://tex.z-dn.net/?f=Area%20%3D%200.5%20%2A42.5%2A%2035.5%20%2A%200.4462)
![Area = 336.602125](https://tex.z-dn.net/?f=Area%20%3D%20336.602125)

Answer:
B) 120
Step-by-step explanation:
Initial problem: 90/x = 3/4
Cross multiply to get:
90*4 = 3x
360 = 3x
x = 120
Check (optional):
90/120 = 3/4
(simplify):
3/4 = 3/4 so it is correct

Answer:
30000
Step-by-step explanation:
30 x 1000
To simplify the equation, you just have to add like terms. This means adding 9.63 and 7.5. Once you've found your sum, which is 17.13, your equation will be <em>N+17.13.</em>
