X = girls
Y = boys
X + y = 428
The sum of the interior angels is 180(n-2). In this case 180(5-2)= 540. So the equation is 540=100+103+4x+(3x+3)+(5x-2). Then solve for x. X=28
Answer:
156 square inches

Answer:
1229 km
Step-by-step explanation:
The missing angle is ...
180° -60° -75° = 45°
Knowing that, the Law of Sines can be used to find the side opposite the 75° angle.
?/sin(75°) = 900 km/sin(45°)
? = (900 km)sin(75°)/sin(45°) ≈ 1229.423 km
The UFO is about 1229 km from KA-12.
