I seriously need help someone lol.

∠B = 43°

Step-by-step explanation:

Hello There!

Remember the exterior angle rule: an exterior angle of a triangle is equal to the sum of its opposite interior angles

That being said we can use this equation to solve for x

108 = 3x + 5 + 2x + 3

step 1 combine like terms

3x + 2x = 5x

3 + 5 = 8

now we have 108 = 5x + 8

step 2 subtract 8 from each side

108 - 8 = 100

8 - 8 cancels out

now we have 100 = 5x

step 3 divide each side by 5

100/5=20

5x/5=x

we're left with x = 20

Now we want to find the value of angle B

Knowing the value of x all we have to do is plug in 20 into x for (2x+3)

2(20)+3=angle b

2*20=40

40+3=43

so we can conclude that angle b = 43

it alot will look like this 4.4

yes because they have the same amount of green and blur marbles.
