9 x 2 = 18
6 x 3 = 18
and 18 x 1 = 18
Factor the numerator and denominator and cancel the common factors.
The answer is 3x.
Answer:
Part 1) 
Part 2) 
Part 3) 
Step-by-step explanation:
Part 1) Find AC
we know that
In the right triangle ABC of the figure
Applying the Pythagorean Theorem

substitute the given values


Part 2) Find the measure of angle A
we know that
In the right triangle ABC
----> by TOA (opposite side divided by the adjacent side)
substitute the values

using a calculator

Part 3) Find the measure of angle C
we know that
In the right triangle ABC
----> by complementary angles
substitute the given value


y - 2 = -3 (x+1)
point slope form
y-y1 = m(x-x1)
looking at the above equation
the slope is -3
