10:4 15:6 20:6 if those aren’t on there I ain’t ur guy
I think it’s 0.4285 or 42/85
see the distance formula to find the length of the sides...
opposite sides equal it could be a rectangle or parallelogram
all sides equal, square or rhombus
adjacent equal, kite
and then the slope is used to check angles
if the product of the 2 lines in -1 the lines are perpendicular (right angle)
the the slopes of 2 lines are the same the sides are parallel.
hope it helps
Answer:
Step-by-step explanation:
= - 
× - ← multiply numerators/ denominators
= 
=
leg = cos(small angle)* hypotenuse
= cos(45)*4 = 2 *Square root of 2 or 2.83cm ( depending on how you need to answer.
