C. 50 I believe. Because it has to be equal to 180 making 2 different angles together to get 180. If that makes sense
Answer:
54 kg
Step-by-step explanation:
Total weight of 7 boys is 392 kg. And other 6 boys total weight is 338 kg.
So the 7th boy's weight is (392-338)=54 kg
Since (AB) ̅≅(AD) ̅ (the lines beside the parentheses are to show that they are lines) we have congruent hypotenuses. (AC) ̅≅(AC) ̅ so legs are ≅ So, es; ΔACB≌ΔACD by HL. The answer is D.Yes; ΔACB≌ΔACD.
Hope this helped!

A regular decagon has 10 equal sides. An apothem is a perpendicular bisector to the side. This means 2 equal right triangle are formed on each side (20 equal right triangles) or 10 equal isosceles triangles.
Using the 10 equal isosceles triangles and A = .5(base)(height)
Base is a side and height is apothem
Area of regular decagon = 10 × .5 × 8 × 12.3 = 492.0 yd²
Answer: 492.0 yd²
