Answer: BC = √5, AC = 2√5
<u>Step-by-step explanation:</u>
= 60°, which means ΔABC is a 30°-60°-90° triangle so we can use the side length formulas: x - x√3 - 2x.
∠C is the 60°. It matches to side AB so: AB = x√3 = √15 ⇒ x = √5
∠A is the 30°. It matches to side BC so: BC = x = √5
∠B is the 90°. It matches to side AC so: AC = 2x = 2(√5) = 2√5

Answer: k = 4, RS = 12, QS = 28
<u>Step-by-step explanation:</u>
proportionality constant k can be found with =
= 4
→ 4 =
→ 4(3) = RS
→ 12 = RS
→ 4 =
→ 4(7) = QS
→ 28 = QS
The area of the composite figure with 3 semicircles connected to 3 sides of a square is (6π+16).
A semicircle is a plane shape that is a part of a circle divided into two equal parts through its diameter.
Analysis:
Since the semicircles are connected to 3 sides of a square 4cm, the diameter of the semicircle is 4cm.
Radius of semicircle = 4/2 = 2cm
Area of a semicircle = π/2 =
/2 = 2π
For three semicircles = 3 x 2π = 6π
Area of square = =
= 16
Area of composite figure = Area of 3 semicircles + area of square
Area of composite figure = (16 + 6π)
In conclusion, the area of the composite figure is (16 + 6π).
