230 times .30 is 69 so sub that from 230 you get 161
Answer:
C = 21.78 and a= 8.88
Step-by-step explanation:
Here, sides b=7 and c=3
Also, Angle B=60
Angle B is between side c and a
It can be solve by cosine rule and sin rule
sin rule says,

cosine rule says,

19 units
Use the absolute value to find the difference between the values. This ensures that no matter which way round the calculation is done the result is the same
| - 13 - 6 | = | - 19 | = 19
or
| 6 - (- 13) | = | 6 + 13 | = | 19 | = 19
Perimeter=2l+2w
2l+2w=272
l+w=136
l+57=136
l=79
Let U = {5, 10, 15, 20, 25, 30, 35, 40} A = {5, 10, 15, 20} V = {25, 30, 35, 40} C = {10, 20, 30, 40}. Find A C.
