Step-by-step explanation:
<u>Heron's Area formula:</u>
- A = , where s is semi-perimeter
- s = 1/2(a + b + c)
We are given two sides and the included angle.
<u>Use the law of cosines to find the missing side:</u>
- a² = b² + c² - 2bccos A
- a² = 77² + 41² - 2*77*41*cos 79
- a² = 6405
- a = 80 (rounded)
<u>Now find the value of s:</u>
- s = 1/2(80 + 77 + 41) = 99
<u>Find the area:</u>
- A = = = 1549.24
The answers are "EN and ZW" and "CV and LR"
Parallel lines can be described as being like the two L's in parallel. Because they are both going in the same directions and have the same slope, they will never touch even if you extended them to infinity.
Answer:
61.7295 (61.7) miles
If I'm reading this correctly, this is just a simple addition equation. You'd add up 23.4865 and 38.243 to get 61.7295 miles, or 61.7 miles.
Hope I helped! ☺
