A 24 -gon has 24 exterior angles. Each exterior angle measures 36024=15 . The interior angle measures 180−15=165 . The sum of the 24 interior angles is then 24⋅165=3960
Read some notes on reflection. If it asks to reflect it on the x-axis youre going to reflect it either on the bottom or top plane. If it asks to reflect on y-axis youre going to reflect it on either the left or right plane.
Answer:
186,666,667 Americans know who the vice president is
Step-by-step explanation:
In this question, we are tasked with calculating the number of USA citizens that know who the vice president is.
Now, in this question, we are made to know that the total population is set at 280 million with 2 out of three knowing who the vice president is.
What this means is that a fraction of the population at 2/3 knows who the vice president is
This fraction is equal to; 2/3 * 280,000,000 = 186,666,666.66666666
This is approximately equal to 186,666,667 people
Answer:
m∠A = 9.1°
m∠B = 10.9°
c = 54.2
The answer is (d)
Step-by-step explanation:
∵ a = 25
∵ b = 30
∵ m∠C = 160°
∴ c² = a² + b² - 2 × ab × cos(C)
∴ c² = 25² + 30² - 2(25)(30) × cos(160) = 2934.5389
∴ c = 54.2
∵ a/sin(A) = b/sin(B) = c/sin(C)
∵ 25/sin(A) = 54.2/sin(160)
∴ sin(A) = (25 × sin(160)) ÷ 54.2 = 0.1577584
∴ m∠A = 9.1°
∵ 30/sin(B) = 54.2/sin(160)
∴ sin(B) = (30 × sin(160)) ÷ 54.2 = 0.18931
∴ m∠B = 10.9°
