Answer:
x = 7
Step-by-step explanation:
I think there may be other ways to do this ... but this is one I guess....
one angle= 90 ( given)
the other = 45 (given)
the third = 90 + 45 + a = 180
(all angles of triangles is 180 [angle sum property])
a = 180 - 135
= 45
The base angles are equal so that means it is a isoscles triangle. In isoscles triangle, two sides are equal , so
if one side is 7
the x is 7 too
(as it cant be the hypothenus)
I think this is right
Answer:
h=12
Step-by-step explanation:
First look at the formula for finding the volume of a cone- 
Next substitute any variables for values you already know- 
Then solve the equation.
Y=2-3(x-7)
You just add +2 to each side and the positive and negative cancel out and it switches it over
Answer: False.
Values that are in common with both circles will be inside both circles. These values will be in the overlapping region of the two circles.
