Answer:
The angles are supplementary to each other (their sum is 180 degrees)
x = 62°
Step-by-step explanation:
(2x+10) + 46 = 180
subtract 56 from each side
2x = 124
divide both sides by 2
x = 62°

ANSWER:
The surface area of the star is 3.2700 x
square kilometres.
EXPLANATIONS:
Diameter of the star = 1.8083 x
Km.
Surface area of the star = 4
Where n is the radius of the star.
So that;
n =
= 0.90415 x 
n = 0.90415 x
Km
Thus,
Surface area = 4 x 
= 326994889
Surface area = 3.2700 x

Therefore, the surface area of the star is 3.2700 x
square kilometres.
