Answer:
6
Step-by-step explanation:

2.2 times 3.3=7.26 because u just do it normally and move the decimal in twice because it's in two place values and there are 2 decimals so u move it twice to the left
The angle immediately below x makes up the third angle of the isosceles triangle whose base angles are 55°. That third angle and x are "vertical" angles, hence equal. The value of x can be found from the sum of angles of a triangle:
x + 55° + 55° = 180°
x = 70°
The appropriate choice is the 2nd one:
70°
By the binomial theorem,

Each term containing a factor 6 is divisible by 3, since 3 divides 6. The remaining 1 and 2 sum to 3, which is also divisible by 3.
Answer:

Step-by-step explanation:
By the definition of an angle bisector, we have that
.
We can add
to both sides to get
.
We can then subtract
from both sides to get
.
We can finally divide both sides by
to get
