Since both of the equations equal Y can substitute one for the Y and say that
X-1=3x+3
-4=2x
-2=x
Answer:
Because they are equal (Right angle)
Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
To solve for j, cross multiply:
4 x 45 = 18 x j
180 = 18j
Divide both sides by 18:
j = 10

Step-by-step explanation:
Soh-cah-toa is a great way to remember:

You just remember the first letters : sine= opposite/hypotenuse , for example.
Each term has a common divisor of
