**Answer:**

b = 71 m

A = 83°

C = 29°

**Step-by-step explanation:**

Many calculators can solve triangles. Apps are available for phone and tablet, or on the internet, like the one used here. In general, it takes less time to use one of these than to type your question into Brainly.

Given two sides and the angle between them, the Law of Cosines is the appropriate relation to use for finding the third side.

b = √(a² +c² -2ac·cos(B))

b = √(76² +37² -2·76·37·cos(67.75°)) ≈ √5015.48

** b ≈** 70.82005 **≈ 71 . . . meters**

One a side and its opposite angle are known, the remaining angles are found using the Law of Sines.

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

A = arcsin(a·sin(B)/b) = arcsin(76·sin(67.75°)/70.82005) ≈ 83.33°

** A ≈ 83°**

C = arcsin(37·sin(67.75°)/70.82005) ≈ 28.92°

** C ≈ 29°**

Or, you can find the remaining angle from 180° -68° -83° = 29°.

X = half width of tent

Tan(40) = 6/x

x = 6/Tan(40) = 7.15

2x = 14.30 feet the width of the tent

Get the angle of pq and divided by 2 then that's your angle for r.

**Answer:**

sorry i dont understand the answer

**There is no Step-by-step explanation **

jk its this

So it says 8 less than, meaning 8 minus the product of 5 and -4, so literally it means subtract 8 from 5X-4

8-5*-4
