Answer:

∠B = 52°

Step-by-step explanation:

Since we know that the sum of all inner angles of the triangle equal to 180°, then we can make the following equation,

5x + 3x + 2x + 20 = 180

10x = 180 - 20

10x = 160

x = 160 / 10

x = 16

Since we know that ∠B = (2x + 20)°, we can calculate the following

∠B = (2x + 20)°

∠B = (2(16) + 20)°

∠B = (32 + 20)°

∠B = 52°

You and your friend collect 180 cans for a food drive. The ratio of cans you collected to cans your friend collected is 4 to 5.

Are you looking for the number of cans you and your friend each collected? If yes, here is the solution:

Let x be the number of cans.

4x + 5x = 180
9x = 180
9x/9 = 180/9 (divide both sides of the equation by 9)
x = 20

Now, substitute the values:
4(20) + 5(20) = 180
80 + 100 = 180
180 = 180

Therefore, you collected 80 cans and your friend collected 100 cans.
