The answer is A. The angles are congruent, meaning 6x+1= 49. Using basic algebra, 6x=48, leaving you with X=8.
If you choose a blue marble first its the probability of 3/12 simplified to 1/3 and then the probability of choosing a red next is 5/11 as you didnt replace the one blue marble

Divide 98 by 7, you get 14.
This is how many starburst are in each packet.
A)
Because the sum of angles in a triangle must equal 180° we can say:
62+α+90=180
α+152=180
α=28°
b)
Since all sides have equal length, all angles must have equal measure. (This is an equilateral triangle). And again, because the sum of the angle must be 180° we can say:
b+b+b=180
3b=180
b=60°
