How would you describe the shape of ribution?

Normal distribution

Step-by-step explanation:

A normal distribution can be easily identified if you can see a "bell shape/curve" in the plotted bar chart or line chart.

With regard to a Bat chart a normal distribution can be identified when most of the tall bars are in the middle and when going from middle to both left and right you see the height of the bars dropping at the same rate both ways.

I have attached an image by editing your attachment. I have shown the "bell shape/curve" or the normal distribution.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
