Question

help

Answer 1

for example the first one
we check the top scale units - from left to right
so how you see on the left part from zero till the line UV there are 56 units
and now you check how many units there are till the line UW so we get there are 104 units
to get the measure of angle VUW just you need subtract from the units quantity of 104 the units quantity of 56 so
104-56 = 48 units
in this way we get the angle measure of VUW = 48 units

in the same way you can calcule the next angles measure too
