Answer:
63 vehicles are not white
Step-by-step explanation:
Well you know that there are 175 total vehicles, and that 64% of those vehicles are white. Therefore the remaining percentage of vehicles must not be white.
100%-64%=36%
This means that 36% of the vehicles aren't white.
Now you must find what 36% of 175 is. The word "of" always signals for multiplication, which is exactly what you need to do here. First start by converting the percentage into decimal form:
36%=0.36
Now you can multiply
175 x 0.36 = 63
63 Vehicles are not white
3.36242487588 is the answer
Since x is across from 148, and arcs opposite inscribed angles = 2×angle, then we can find x first.
We could set the 2 angles equal to 180 or their arcs equal to 360.
360 - (2×148) = x-arc
x-arc = 360 - 296 = 64
x = x-arc ÷2 = 64/2 = 32
Now for angle A we plug in for x:
A = 2x+1 = 2(32)+1 = 65°
It would be rounded to 20.
hope this helps you
