The answer is 30°.
Rule: All three sides must add up to 180
°. 
Since A=60 and the side vertical to the angle which is 90° then side C would be C=90° and that adds up to 150°, so you can conclude that angle B is 30°.
I hope I helped!

what is the circumference of a circle that has a radius of 8 units use 3.14 (pie) and round to the nearest hundredth
SashulF [63]

Remember that the formula for the circumference, C, of a circle is:

C = d \pi


In this case, we are not given the diameter. However, remember that the diameter is equivalent to two times the radius of a circle. Thus,

d = 2 \cdot 8 = 16,

and we can say the circumference of our circle is:

C = 16 \cdot 3.14 = 50.24 \,\textrm{units}


The circumference of our circle is 50.24 units.


<em>Also, a little side note not relating to the question:</em>

<em>Remember that \pi is spelled as "pi" not "pie." Pie is a dessert, while pi is a mathematical constant.</em>
