Does anybody know the answer?

Answer:

y=140°

Step-by-step explanation:

Method 1.

The exterior angle theorem tells us that y=20+120=140

Method 2.

Solve for x first., then use that to solve for y.

The sum of the interior angles of a triangle is 180, so we can get x by doing 180-20-120=40.

y and x make a straight angle which is 180°, so we can get y by doing 180-40=140

The table shows the number of balls, by sport, in the gym.
n200080 [17]
A. The ratio of soccer balls to all balls are 4:25

All the balls combined are 50 balls

8 of the balls are soccer balls so that makes the ration 8:50

In the simplest form it is 4:25 since you can't divide 4 or 8 by 50, you can use 2
and you get 4:25 as your answer
So it is A.
