For the first triangle the sum of angles in any given triangle is equal to 180 degrees.
The equation for the first triangle would be: 60+80+x+51= 180
Solving it we get: 191+x=180
x=-11.
The second triangle’s equation is: 90+45+52+x= 180
Solving it we get: 187+x=180
x=-7
The third triangle’s equation is: 4+7x= 90
This is because it is a right angle.
Solving it we get: 12.2 (rounding)
x=about 12.2
For the fourth triangle the equation is: 6x-5+5x=105 (we subtract 75 to 180 to get the sum of the other two angles)
Solving it we get: 11x=110
x=10.
Hope this helps! ( and if you can please give brainliest, it would mean a lot!)
No because the sides are different if they were the same they would be a right triangle

Answer:</h3>
<em>Your answer would be y=x+3/12</em>
<h3>
Step-by-step explanation:</h3>
Firstly, you'll switch sides of the equation.
<em>y=12x+3 ---> x=12y-3</em>
Next, add 3 to both sides.
<em>x=12y-3 ---> 12y-3+3=x+3</em>
Simplify it.
<em>12y-3+3=x+3 ---> 12y=x+3</em>
Then, divide both sides by 12.
<em>12y=x+3 ---> 12y/12 = x/12 + 3/12</em>
Simplify once more.
12y/12 = x/12 + 3/12 --- y= x+3/12
<u>y=x+3/12 would be your answer.</u>
