yuradex [85]

Answer:

Hello,

answer is 204 in base 10 or 21120 in base 3

Step-by-step explanation:

((202)_3)^2=(202*202)_3=(112211)_3\\\\((112)_3)^2=(112*112)_3=(21021)_3\\\\(112211-21021)_3=(211120)_3=(204)_{10}\\\\\\\\\\Other\ way\\\\((202)_3)^2=((20)_{10})^2=(400)_{10}\\\\((112)_3)^2=((14)_{10})^2=(196)_{10}\\\\(400-196)_{10}=(204)_{10}=(21120)_3

Circles M and K are congruent, QR is congruent to LN and OP is congruent to VW. Find x.
guajiro [1.7K]

QR = LN, so

-2x = -3y + 3

OP = VW, so

-6x =-6y + 18

(-2x = -3y + 3)*(-2) ------> 4x = 6y - 6

-6x = - 6y + 18

4x = 6y - 6

<u>-6x = - 6y + 18</u>

-2x = 12

x= - 6

The figure shows a square, a regular pentagon and a regular hexagon put together. What is the measure of ∠BAC
Elan Coil [88]

Answer:

42

Step-by-step explanation:

One angle of a regular pentagon = 108°

One angle of a regular hexagon = 120°.

One angle of a square = 90°

∴ ∠BAC = 360 – (108 + 20 + 90) 360 – 318 = 42°
