Answer:
19. C
20. D
21. B
22. A
Step-by-step explanation:
If an angle is subtended from an arc and it goes to the opposite end of the circle, the angle is HALF of the measure of the arc. If it goes to the center, it is SAME measure as arc.
19.
Arc BC is DOUBLE of Angle BAC, so
78 * 2 = 156
Answer is C
20.
Arc BEC is DOUBLE of Angle BAC, so
114 * 2 = 228
Answer is D
21.
Angle ABC is HALF of Arc AC, so
Angle ABC = 110/2 = 55
Answer is B
22.
Angle ABC is HALF of Arc AC, so
Angle ABC = 218/2 = 109
Answer is A
Answer:
n=64 and n+1=65
Step-by-step explanation:
64 + 65 equals 129
The actual block is 1800 feet long and 1260 feet wide. We know that 1 foot is equivalent to 12 inches.
Luke is now using the Feet scale measurement.
Solving for the area in square inches is shown below:
Area = L * W
Area = (1800 feet *12 inches/1 foot) * (1260 feet *12 inches/1 foot)
Area = 326.592 x10^6 inches²
In this case, 40ft is the vertical distance from the ground, which is the height. This means that the kite and the string form an angle with the horizontal ground. A right angled triangle is formed. Use the inverse of sine to get the angle.
Answer: a) For 20X1 = 7.50; 20X2= 7.50
b) For 20X1 = 5.50; 20X2= 6.00
