Answer:
side c = 10.2
A = 52.6°
B = 37.4°
Step-by-step explanation:
c² = 8.1² + 6.2²
c² = 104.05
c = 10.20049018
Using cosine law:
8.1² = 10.2² + 6.2² - 2(10.2)(6.2)cos
cosA = 7687/11648
A = 52.57199409
A = 52.6°
B = 180 - 90 - 52.6 = 37.4°
Nope. its y=3x-1. the y intercept is -1, so we put that at the end. And if we take 2 points on the line and use y/x, we get 3/1 or 3, and this is our slope. Also the line is going up so its not negative
The sum of the perimeters of two congruent triangles is TWO times the perimeter of one of them.
hope it helps

Answer:
A. y = –5x – 27
Step-by-step explanation:
You would need a new y-intercept in order for this to be parallel. So you use the points given and the slope and fill it in. 3=-5(-6)+b. 3=30+b. Then subtract 30 from both sides. -27=b. Then just put it all back into slope intercept form. y=-5x-27.
y = –5x + 3
slope of the given line by comparing with y=mx+b is
m= - 5
Concept is that the slope of parallel lines are equal so we need a line with slope same as m=-5
and passes through point (-6,3)
Equation using the point slope equation
y-3 = -5 (x-(-6))
y-3=-5(x+6)
y-3= -5x-30
y= -5x -27
