What is the value of s to the nearest whole number?
a) 13
b) 12
c) 14
d) 10

Given:

In given Δ RST,

RS = 9, ST = 8 and ∠S = 110°

To find the value of another side RT (s).

Formula

By cosine law we get,

Now,

Putting,

b=9, c=8, A = 110° and a=s we get,

or,

or,

or,

or,

or,

Hence,

The value of s is 14. Option C.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
