Answer:
8. 105 degrees
9. 75 degrees
10. 105 degrees
Step-by-step explanation:
The given angle is 75 degrees. The four angles together make up 360 degrees because quadrilaterals have a measurement of 360 degrees on the inside. The angle that is 75 degrees and angle 2 are opposites (I forgot the math word, sorry) so they are the same degrees. So we know that angle 2 is 75 degrees. Angles 1 and 2 are vertical pairs, as well as the given angle and angle 3. We know that vertical pairs equal 180 degrees. 180 - 75 = 105 degrees. Now we know that both angle 1 and 3 are 105 degrees. You could also find the measurment of angle 1 and 3 by making an equation.
Given angle + Angle 2 + Angle 1 + Angle 3 = 360 degrees
(75 + 75 + 2x = 360)
150 + 2x = 360
2x = 210
x = 105
Answer:
a would be different because if it was negative it would be positive because absolute value is positive unless it is negative absolute value
Step-by-step explanation:
y=x(-2,7)

Answer:
x = 2. The answer is 2
Step-by-step explanation:
You don't have to use the tiles if you don't want to... I didn't use the tiles. Ok so,
In order to get x by itself you need to first add 5 to both sides. Once you do that it should look something like this
4x-5 +5 = 3+5
-5 and +5 both cancel out just leaving you with 4x, and 3+5=8. So now it should look like this.
4x = 8
Now, you just have to divide 4 to both sides
4x/4 = 8/4
Both 4's cancel out leaving you with x and 8 divided by 4 equals to 2.
x = 2
TAADAA!!
I hope this helps! Have a good day!
P.S
No one sucks at math dude you just gotta practice lol :D
