4(x+2)=4x+8
2(x-1)=2x-2
2(x+1)=2x+2
You use disruptive property when solving equations like this.
For this case, what we should know is that a polygon is a geometric figure with n sides that is closed. It is usually the union of straight lines.
On the other hand, in order to find the area of a figure, we need it to be closed.
Therefore, the edges of an area are confined by snap points.
Answer:
FALSE
Answer:
396°
Step-by-step explanation:
Difference = 357 -(-39) = 357+38 = 396°
Answer:
m < amc = 54°
Step-by-step explanation:
< amb and < bmc are complementary angles whose sum equals 90°.
Therefore, to find the value of 2x°, we must first solve for x.
We can establish the following equality statement:
< amb + < bmc = < amc
< 2x° + (x + 9)° = 90°
Combine like terms:
2x° + x° + 9° = 90°
3x° + 9° = 90°
Subtract 9 from both sides:
3x° + 9° - 9° = 90° - 9°
3x = 81°
Divide both sides by 3 to solve for x:
3x/3 = 81°/3
x = 27°.
Since x = 27°, substitute its value into 2x° to find m < amc:
2x° = 2(27°) = 54°
Therefore, m < amc = 54°
