Answer:
Step-by-step explanation:
To find the surface area of a cone, one uses the following formula,
Where (r) is the radius of the base of the cone, and (h) is the height of the cone, (
) represents the numerical constant (3.1415...). In order for this formula to work, one needs the height of the cone. This can be found using the Pythagorean theorem. One can form a right triangle with the base's radius, the side length, and height of the cone, then solve for the height of the cone. The Pythagorean theorem states the following,
Substitute,
Simplify,
Inverse operations,
Now one can use the formula to find the surface area of a cone, substitute in the given values, and solve,
Substitute,

Answer:
42 degrees, and 48 degrees
Step-by-step explanation:
set up an equation to find x, the first angle measure
(x+6)+x=90
then simplify:
2x+6=90
2x=84
x=42
So, the first angle measure is 42, now to find the second angle measure, add 6 to 42, and you will get 48.
