Check the picture below, those are the x,y pairs or cosine, sine values pair.
now, this is from the Unit Circle, and therefore the hypotenuse or radius wil be 1.
so, just plug in those values... hmmm lemme do the tangent, so you see the division of two fractions.
Answer:
947.4 cm
Step-by-step explanation:
Use the slope formula to determine the slope of the two points. Since (0,12) is the y-intercept it is already given.
Y = x +12
Answer:
50
Step-by-step explanation:
x + 30 = 180 - 2x [vertically opposite angles]
x = 180 - 30 - 2x
x = 150 - 2x
x + 2x = 150
3x = 150
x = 150/3
x = 50
