Answer:
AB = 3 and AC = 4
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= ( cross- multiply )
30AB = 90 ( divide both sides by 30 )
AB = 3
and
= , substitute values
= ( cross- multiply )
30AC = 120 ( divide both sides by 30 )
AC = 4
Answer:
90 and 10
Step-by-step explanation:
90 + 10 = 100
90 - 10 = 80
Answer:
Option 1)
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
Remember that
so
The solutions are
and
First you must find the slope, by using the equation y2-y1/x2-x1
then you plug the slope and one of the given points into the equation
y-y1=m(x-x1)
so the answer is
y-3=-4/5(x-0)
