Answer:
Step-by-step explanation:
a. sin^-1(sin theta) = theta
(1/sin)(sin theta) = theta
<em>the sines cross out</em> theta = theta
b. cos(cos^-1x) = x
cos(x/cos) = x
<em>the cosines cross out </em>x = x
Answer:
63 miles
Step-by-step explanation:
2/70 = 1.8/x Cross multiply
2x = 70 * 1.8 Combine
2x = 126 Divide by 2
x = 126/2
x = 63
The actual distance is 63 miles.
I'd say the bottom answer is the best answer
Answer:
Step-by-step explanation:
84/4=21
Square root of 4=2
The answer is line A. Because 1 is the Y - Inrercept in the equation and Line A fits that. and it goes up 2 over 1 which is the slope in the equation
