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.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
