Answer:
726 rpm
Step-by-step explanation:
The angular speed is not dependent upon the radius. The rotational speed is 726 rpm at any radius.
80*x + 210 = 490 ;
80*x = 280 ;
x = 280÷80 ;
x = 3.50 ;
ok so you are given 61degrees and you want to find b you can ignore that weird line on the top left because its not needed but
you can see that 61degrees is next to b and they are on a strait line so that means that they have to equal to 180
so 61 + b = 180
b = 119
so b should equal 119
