<span>The chance of rolling a 1 is 1/6 because there are 6 sides on a die and only 1 of those is 1</span>
So a triangle is always 180°.
If one angle is 90° then we can subtract that from the 180° to find out how much the other two will be.
180°-90°=90°
So the other two angles added together will have to equal 90°.
There is an X intercept at x=-8
There is a y intercept at y=4 (0,4)
8.64
thats 12% of 72
hope this helps :]
