Step-by-step explanation:

first of all, as the sum of all angles in a triangle is always 180°, the missing angle B is

B = 180 - 89 - 30 = 61°

the law of sine is

a/sin(A) = b/sin(B) = c/sin(C)

where the sides are always opposite of the associated angles.

14/sin(61) = AB/sin(30) = BC/sin(89)

BC = 14×sin(89)/sin(61) = 16.00451901...

so, 16 is the correct answer.

So:

s² + s(s + 6) = 56

s² + s(s + 6) - 56 = 0

<u>Solution:</u>

Given, The Montegro Flooring Company can replace 200 square feet of carpet with tile in one day

They accept a job replacing carpet with tile in an apartment that measures 977.5 square feet

We have to find how many days will it take the Montegro Flooring Company to complete this job?

Now, according to given information,

200 square feet ⇒ 1 day

Then, 977.5 square feet ⇒ n days

Now, by chris cross method

$\begin{array}{l}{200 \times n=1 \times 977.5} \\\\ {200 n=977.5} \\\\ {n=\frac{977.5}{200}=4.8875}\end{array}$

Hence, the company requires 5 days approximately.
