Answer:
10.8 cm
Step-by-step explanation:
Using cosine law
g² = 7.1² + 6.7² - 2(7.1)(6.7)cos(103)
g² = 116.7018433
g = 10.80286274
Answer:
Slope: 7/4 Equation: y = 7/4x
Step-by-step explanation:
To find the slope check how much the line goes up when it goes to the right by 1. You can see in the picture that every time it goes to the right 8, it goes up by 14, so the slope is 14/8 = 7/4.
Since it goes through the point (0, 0) and the slope is 7/4, you know the equation would just be y = 7/4x
