Answer to written question:
3x + 10x + 7x = 180
Combine like terms
20x = 180
Divide by 20
x = 9
Smallest angle 3x = 3*9 = 27 degrees
Answer to question in picture:
30/6x-2 = 36/5x + 13
Cross multiply
30(5x + 13) = 36(6x-2)
Distribute
150x + 390 = 216x - 72
Subtract 150x
390 = 66x - 72
Add 72
462 = 66x
Divide by 66
x = 7
Remember
so
take the log of both sides
or
B is the answer
I think we’re talking about the 15, the smallest number for 15 would be 3. Because 3 x 5 = 15
The three remaining slices would form 108 degrees.
Hope this helped (and that I was right) =P
