Best ResponseYou've already chosen the best response.1if it asks for angle 1, that is 1/2 the difference of the two arcs i.e. (big  small)/2

Best ResponseYou've already chosen the best response.1fill in what you know, then use algebra to "solve for VU" can you do that ?

Best ResponseYou've already chosen the best response.1\[ \frac{VU 20}{2} = 30 \] I would start by multiplying both sides by 2

Best ResponseYou've already chosen the best response.0I was thinking about doing that, but then I started to second guess myself

Best ResponseYou've already chosen the best response.1you do this \[2\cdot \frac{(VU 20)}{2} = 30 \cdot 2\] you can think of the left side as multiplying fraction times fraction (top times top and bottom times bottom) \[ \frac{2}{1} \cdot \frac{(VU 20)}{2} = 30 \cdot 2\] \[\frac{2(VU 20)}{2} = 30 \cdot 2\] or \[ \frac{2}{2} \frac{(VU 20)}{1} = 30 \cdot 2\]

Best ResponseYou've already chosen the best response.1in other words you should get VU 20 = 60

Best ResponseYou've already chosen the best response.0Okay. So you don't multiply 20 by 2?

Best ResponseYou've already chosen the best response.1remember to how to add or subtract fractions: \[ \frac{VU}{2}  \frac{20}{2} = \frac{VU20}{2} \] you can do it the other way round: \[ \frac{VU20}{2}= \frac{VU}{2}  \frac{20}{2} \] and simplify 20/2 to 10 \[ \frac{VU}{2}  10 = 30 \] now add 10 to both sides \[ \frac{VU}{2}  10 +10 = 30+10 \\ \frac{VU}{2} = 40 \]

Best ResponseYou've already chosen the best response.1I guess you have to get the idea that \[ \frac{complicated\ stuff}{2} \cdot 2 = complicated\ stuff \]
