Enter the patriot equivalent to Tan (A)

And

Enter the ratio equivalent to cos (B)

Step-by-step explanation:

Given

See attachment for triangles

Solving (a)

The tan of an angle is:

From the given triangle.

So, we have:

Solving (b)

The cos of an angle is:

From the given triangle.

So, we have:

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
