A new library, L, is to be built at some point along a straight road, R, such that its distance from train station, T, is the sh
andreyandreev [35.5K]

Answer:

Coordinates of the new library is (150, 70)

Step-by-step explanation:

To get the shortest possible distance means that line from point T to point R has to be perpendicular.

Now, the equation of R is given as;

y = x - 80 - - - (1)

For T to be perpendicular, it means it will have a slope equal to the negative reciprocal of line R.

Thus, slope of T is -1/1 = - 1

Thus, using line - slope intercept of y = mx + c, we can find equation of T as;

140 = -1(80) + c

140 = -80 + c

c = 140 + 80

c = 220

Thus, equation is;

y = -x + 220 - - - (eq 2)

Adding equation 1 to equation 2,we have;

y + y = 220 - 80

2y = 140

y = 140/2

y = 70

Putting 70 for y in eq 1 gives;

70 = x - 80

x = 70 + 80

x = 150

Thus;

Coordinate of the new library is (150, 70)

When you use sine and cosine to solve the value of 0 for the two triangles below, you obtain the same value.
Vikki [24]

Answer:The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).

Step-by-step explanation:

In these definitions, the terms opposite, adjacent, and hypotenuse refer to the lengths of the sides.

For example, if we want to recall the definition of the sine, we reference S\blueD{O}\purpleC{H}SOHS, start color #11accd, O, end color #11accd, start color #aa87ff, H, end color #aa87ff, since sine starts with the letter S. The \text{\blueD{O}}Ostart text, start color #11accd, O, end color #11accd, end text and the \text{\purpleC{H}}Hstart text, start color #aa87ff, H, end color #aa87ff, end text help us to remember that sine is \text{\blueD{opposite}}oppositestart text, start color #11accd, o, p, p, o, s, i, t, e, end color #11accd, end text over \text{\purpleC{hypotenuse}}hypotenusestart text, start color #aa87ff, h, y, p, o, t, e, n, u, s, e, end color #aa87ff, end text!
