Divide each side of the equation by -2. (Or multiply each side by -1/2 ... same thing.) Then step quickly to one side, to avoid being struck as the solution jumps off of the paper at you.

If you're trying to solve for y
-2y = 8
Divide -2 to both sides
$\frac{-2y}{-2} = \frac{8}{-2}$
Cancel out the -2 on the left, Divide the -2 to the 8 on the right so
y = -4

These two rectangles are similar which is a correct proportion for corresponding sides

hammer [34]

to make the proportion we make the ratio of the similar sides

For example

4/8 = 12/x

or we can write it as 4/12 = 8/x

or 12/x = 4/8

So last option is correct

Answer:

∠A = 45°

Step-by-step explanation:

The sum of angles in a triangle = 180°.

That means in the triangle ABC, ∠A + ∠B + ∠C = 180°.

Given ∠B = 90° and ∠C = 45°.

⇒ ∠A + 90° + 45° = 180°

⇒ ∠A = 180 - 90 - 45

⇒ ∠A = 45° is the required answer.
