Answer:
see explanation
Step-by-step explanation:
(a)
OC = OB ( both radii of the circle )
Thus Δ BOC is isosceles with congruent base angles.
∠ BOC = ∠ BCO = 50°
(b)
∠ ACB = 90° ( angle in a semicircle ), then
∠ ACO = 90° - 50° = 40°
OA = OC ( both radii of the circle )
Thus Δ ACO is isosceles with congruent base angles.
∠ BAC = ∠ ACO = 40°
Answer is G
with or without the 10, you are going to get 5 as your answer to the equation
The dimension of one side of the stamp was 2 centimeters
Step-by-step explanation:
The formula of the area of any square is A = l², where l is the
length of the side of the square
lance bought a square postage stamp to a mail a card to his cousin
∵ The stamp has 4 square centimeters
∴ The area of the stamp = 4 cm²
∵ The stamp shaped a square
∵ The formula of the area of the square is A = l²
- Equate the formula of the area of the square by the area of the stamp
∴ l² = 4
- Take √ for both sides to find l
∴ 
∴ l = 2 cm
The dimension of one side of the stamp was 2 centimeters

Answer:
x = 5
Step-by-step explanation:
A = hb/2
10 = 4(x)/2
10 = 2x
x = 5
im not sure if this is right but get back to me if it isn't
Hmmm the easiest way I can imagine to explain this is as follows:
4 times 3 is like 3 added to itself 4 times.
so 4×3= 3+3+3+3= 12. I'm not sure if that's what you meant by drawing a model though.
