Solution, x <= 10/3 and y < 5 - x/2 x > 10/3 and y < -2(x - 5) Google for an online graph calculator. You will be able to input the equations and the program will show you a graph.

If you sketch this out you will have a right triangle, I will call ABC. A is the vertex = angle of depression AC (side b) = base = 1400 feet BC (side a) = leg = 1100 feet AB (side c) = hypotenuse = distance to landing site To find angle A (angle of depres...

C = 180 - A - B = 180 - 45° 48' 36" - 61° 2' 13" = 73° 9' 11" Law of sines: a/sinA = c/sinC a = c.(sinA/sinC) = 426.(sin(45° 48' 36"))/sin(73° 9' 11")) a = 426*0.749186 a = 319.153

okay i was able to get c*sin(A)= 1.8555387 but i was lost after that. I couldn't reproduce the same answers u have. value logarithm c 2.6294096 sin(A) 1̅.8555387 2.4849483 [ADD] sin(C) 1̅.9809493 a 2.5039990 [SUBTRACT] Anti-log 319.1530 (length of c)

or sin (255°) = sin (180° + 75°) = - sin 75° [The terminal side of the angle lies in quadrant III, so the sine function is negative.] = - sin (45° + 30°) = - (sin 45°cos 30° + cos 45°sin 30°) [Use sin (A + B) = sin A cos B + cos A sin B.] = - [( Square ro...
