Step-by-step explanation:
<em>Angle sum property of triangle states that the sum of interior angles of a triangle is 180°</em>
So,

Answer:
the first step is to use the
✔ Subtraction
property of equality to combine the constant terms.
The second step is to use the
✔ Division
property of equality to isolate the variable
Step-by-step explanation:
edge 20 20
Check the picture below.
and since a triangle has a sum of 180° for all interior angles.
A = 180 - 39.34 - 25
A = 115.66

make sure your calculator is in Degree mode.
Answer:
Instead of moving the 3x to the opposite side of the equation they moved the 2x. And the correct answer is x=-6 not x=6.
Step-by-step explanation:
Student Work:
2(x + 4) – 8 = 3x+10-4
2x + 8–8 = 3x + 6
2x = 3x + 6
- 3x – 3x
X = 6
My work:
2(x+4)-8=3x+10-4
2x+8-8=3x+6
2x=3x+6
-x=6
x=-6
Answer:
6
