If it cannot be solved just comment because that is possible

x = approx. 25.7 and y = 12

Step-by-step explanation:

Isosceles triangles have 2 equal sides and 2 equal angles and there are 180 degrees in a triangle.

3x + 3x + x = 180

7x = 180

x = approx. 25.7

3(25.7) + 3(25.7) + 25.7 = 180

77.1 + 77.1 + 25.7 = 180

179.9 approx. = 180

7y + 7y + y = 180

15y = 180

y = 12

7(12) + 7(12) + 12 = 180

84 + 84 + 12 = 180

180 = 180

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
