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:
D
Step-by-step explanation:
I did it
Answer:
It would be worth $5,040 after 7 years
Step-by-step explanation:
Multiply 40% by 7 and get 280, then turn it into a percent, .280, finally multiply it by $18,000 to get $5,040
You have to finish writing the question for someone to answer
40 times 8 =320 Also 4 times 10 = 40 times 8 equal 320 30 times 10 equal 300. 5 times 60 = 300. 5 times 6 tens = 30 tens = 300
