Question

@f 27%(10 6:28 PM webassign.net ill AT&T; Two points are given in polar coordinates by1.20m, 50) and ,0-0340 m, respectively. What is the distance between them? Need Help? For the triangle shown in the figure below what are each of the following? (Let y = 4.00 m and r = 5.00 m. Assume the triangle is a right triangle.) (a) the length of the unknown side x (b) the tangent of (c) the sin of Need Help? L In the figure below, find each of the following (a) the side opposite (b) the side adjacent to (c) cos (d) sin (e) tan

Explanation / Answer

14.

In right angle triangle

x^2 + y^2 = r^2

x = sqrt (r^2 - y^2)

x = sqrt (5^2 - 4^2) = 3.00 m

B.

tan theta = height/base = y/x = 4/3 = 1.33

C.

sin phi = Height/Hypotenuse = x/r = 3/5 = 0.6

15.

A. side opposite theta = 3.00 m

B. side adjacent to phi = 3.00 m

C.

cos theta = Base/Hypotenuse = 4/5 = 0.8

D.

Sin phi = Height/Hypotenuse = 4/5 = 0.8

E.

tan phi = Height/base = 4/3 = 1.33
