Answer:
231.9ft
Step-by-step explanation:
We would be solving this problem by using the cosine rule.
The length = (pq)² + (qr)² -2 * pq * qr * cos102⁰
= 120² + 175² - 2*120*175 (-0.2079)
= 14400 + 30625 + 8731.8
= 53756.8
Length² = 53756.8
We take the square root of both sides
Length = √53756.8
Length = 231.89 feet
This is the length of the wire that is needed.
Thank you
Answer:
the graph's slope-intercept is 3 or 3/1. you do this by finding the rise over run (how many squares does it go up, and how many does it go over).
The Y-intercept is -2. You can always find this by using the formula y= mx + b. Whatever number is in the place of "b" is the y-intercept.
I'm going to take a guess and say you're in Algebra 1. Either that or Pre-Algebra. This stuff took me a little while to full grasp, so don't worry! YOu'll understand it soon enough!
