Complementary angles total 90°.
∠A + ∠B = 90°
∠A + 60° = 90° . . . . substitute the given information
∠A = 30° . . . . . . . . . subtract 60° from both sides of the equation
The angle that is complementary to ∠B measures 30°.

Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r
V = 4/3 π7^3
Evaluate the exponent
V = 4/3 π 343
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.
v= (4/3*343)π
v=1372/3π
If we want an exact answer, multiply 1372/3 and pi
v=1436.75504
So, the volume is 1436.75504 or 1372/3 π cm^3
3x = x + 8
-x -x
2x = 8
/2 /2
x = 4
since angle L and N are the same you would set the 2 sides equal to each other
