Answer:
a
Step-by-step explanation:
it's non-linear
Answer:
Do the opposite operation
Step-by-step explanation:
If there is a coefficient like 3x, you have to divide the 3 on both sides. This is because 3x is equivalent to 3*x. The opposite of multiplication is division.
Answer:
x=36
Step-by-step explanation:
The angles in a triangle must add to 180 degrees.
Therefore,
x+65+79=180
Add 65 and 79
x+144=180
We want to solve for x. In order to do this, we have to get x by itself. 144 is being added to x (+144)The opposite of addition is subtraction, so subtract 144 from both sides(-144)The +144 and -144 will cancel out, and leave x by itself.
x+144-144=180-144
x=180-144
x=36
Let’s check our answer. Add all the angles together, and make sure they equal 180 degrees.
x+65+79
We know x is equal to 36, so we can substitute it in
36+65+79
180
The 3 angles add to 180, so we know that x=36
Answer:
x = 90
Step-by-step explanation:
We use the Definition of Corresponding Angles to help us solve for <em>x</em>:
∠1 = ∠4
Step 1: Write out equation
3x - 160 = x + 20
Step 2: Solve for <em>x</em>
2x - 160 = 20
2x = 180
x = 90
