Answer:
the idea behind the recurring decimal as a fraction, is to first off, multiply or divide by some power of 10, in order that we leave the recurring decimal to the right of the decimal point.
then we multiply by a power of 10, in order to move the repeating digits to the left of the decimal point, anyhow, let's proceed.
notice, we first divided by 10, to move the decimal point over to the right by 1 slot, then we multiplied by 100, to move it two digits over the decimal point, namely the repeating "12", thus we use 100. i think

Answer:
∠x = 63°
Step-by-step explanation:
The exterior angle added with the measure of ∠BAC will equal 180, since they will form a straight line, so we can calculate the measure of ∠BAC:
128 + x = 180
x = 52
∠BAC = 52°
The angles in a triangle all add up to 180°, so we can set up another equation to find x:
52 + 65 + x = 180
117 + x = 180
∠x = 63°
Answer:
3.2÷0.32×(0.73+0.27)^2= 10

Answer:
70 degrees, 21 degrees, 37 degrees
Step-by-step explanation:
For the rectangle
- Angle B= 90 degrees<em> (right angle)</em>
Find Angle AED = 180-46-90=44 degrees
All angles add up to 180 so we can find x
66+44=110, therefore Angle x = 180-110=70 degrees
XYZ is equilateral therefore all angles = 60 degrees
This allows us to find angle WZX, 180-60=120
Angle X=180-120-39=21 degrees
PQR is isoceles so the base angels are equal QRP=71 degrees
180-71=109 degrees. 180-109-34=37 degrees = Angle X
Good Luck!!
