Answer:





Step-by-step explanation: the other angle is equal to his simmetrical, cause the triangle is isosceles, so is value is x. The sum of the angle in a triangle must be 180°
The ratio is 2:3 for the side lengths of the triangles.
so 6:9 is one side and 5:x would be the other side
2/3 of five is 3.33 and multiplying that by 2 gives you 6.67
All i know is that if the radius of a circle is 4 feet, the the diameter is 8 feet. Sorry, I don't know the rest.
5 out of 12 = 5/12
Those are
1 - 106
2 - 137
4 - 120
6 - 195 and
8 - 139
12 would be considered a natural number, whole number, and an integer
Hope this helped
