So, use the distance between two points formula:squareroot((x2-x1)^2+(y2-y1)^2)
squareroot((-7--4)^2+(8-7)^2)
squareroot((-3)^2+(1)^2)
squareroot((9+1)
squareroot(10)
squareroot 10 can be simplified to 3.2 units

Answer:
Step-by-step explanation:
take 40 degree as reference angle
using cos rule
cos 40=adjacent/hypotenuse
0.76=5/x
0.76x=5
x=5/0.76
x=6.578
x=6.58
Answer:
0.5 x 10^3
Step-by-step explanation:
(2.5 x 10^7) /(5 x 10^4)
Divide 2.5 by 5 and subtract the powers. We are subtracting the powers because we are dividing. If we were multiplying, we’d add the powers .
This can be written as
2.5/5 x 10^7-4
0.5 x 10^3
