Answer:
A
Step-by-step explanation:
We can write this as Sinx by "flipping" the 
.
So we will have: 
From basic trigonometry, we know the value of 
of sine is of the angle 
<em>But when is sine negative? </em>Either in 3rd or 4th quadrant. But the answer has to be between 0 and 
, <em>so we disregard 4th quadrant.</em>
<em />
<em>To get the angle in 3rd quadrant, we add π to the acute angle of the first quadrant (which is π/4 in our case).</em><u><em> Thus we have:</em></u>
A is the right answer.
Answer:
B
Step-by-step explanation:
The intercepted angle is given as "34x+4"
The arc is 196.
Any intercepted angle of an arc that falls in the opposite circumference, it will have a measure half that of the arc intercepted.
Hence,
34x+4 = (0.5)(196)
34x + 4 = 98
34x = 98 - 4
34x = 94
x = 94/34 = 2.76
Answer choice B is right.
Answer:
m=36×20
Step-by-step explanation:
A hybrid SUV uses 36 miles per gallon in the city.
The equation that could be used to find how many miles a hybrid SUV can travel in the city on 20 gallons of gas is m=36×20.
