I know that it is 151 but how

directrix · Answer

I think a proportion will give the angle.

42% = 42/100

42/100 = x/360 where x is the measure of the central angle.

Cross multiply to get:

100x = 42*360

Solve that for x and let me know what you get.

okay so I multiplied 42 and 360 and got 15,120 so I divided that by 100 and got 0.1512 <---- my answer

directrix · Answer

I got 151.2

100x = 42*360

x = 15120/100

x = 151.2
