A triangle adds up to 180 degrees so it would be 70
P.S. I think
P.P.S Sorry if its wrong
<h3>
Answer: Choice B. x = 4 and x = 3</h3>
Work Shown:
x^2 - 7x = -12
x^2 - 7x + 12 = 0
(x - 3)(x - 4) = 0 ... see note below
x - 3 = 0 or x - 4 = 0
x = 3 or x = 4
Note: we're looking for two numbers that multiply to 12 and add to -7. Those two numbers are -3 and -4, so that's where the factorization (x-3)(x-4) comes in. After this step, you set each factor equal to zero and solve for x.
your answer is the first one, MNO is similar to GHK
the sum of the interior angles of a triangle is 180°
MNO
180 - 22 - 79 = 79° (angle N)
GHK
180 - 79 - 79 = 22° (angle K)
From here you see that they have the same angles, so they are similar.
The given expression is a perfect square trinomial.
<h3>
How to classify the given expression?</h3>
Here we have the expression:
Notice that we can rewrite it as:
Then we can see that inside the parenthesis we have a difference of squares, but it is squared, so if we define:
We will have:
Which is in fact, a perfect square trinomial.
