I really really need help Idont understand it

angle A and angle B both equal 150 degrees

Step-by-step explanation:

angle A and angle B are congruent

so you take both equations and equal them together

8x-10=3x+90

   +10      +10

8x=3x+100

-3x -3x

5x=100

/5     /5

x=20

Now that you have that, you plug it into the equations. You only plug it into one because they are both equal

Angle A = 8(20)-10

8*20= 160

160-10= 150

Hope this helps :D

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

$12. that is my answer.
