Answer:
Two geometrical shapes which are identical in shape and size are said to be congruent. We use the symbol '≅' to denote congruence.
Step-by-step explanation:
Complementary angles are two angles whose measures add to a sum of 90 degrees. This can be expressed as the following formula:
A1 + A2 = 90
Substitute any known values into the equation above:
(2x + 1) + (x – 7) = 90
2x + 1 + x – 7 = 90
Combine like terms:
3x – 6 = 90
Add 6 to both sides of the equation:
3x = 96
Divide 3 from both sides of the equation:
x = 32
When (2x + 1) and (x – 7) are complementary, “x” is equal to 32.

Answer:
3g = 30
Step-by-step explanation:
Well, lets check each one to see if any leaves g = 0
12g = 0 (Given)
<em>÷12 ÷12 </em>(Get "g" on its own)
g = 0 (0 ÷ 12 = 0)
We know it is not this one since g = 0
3g = 30 (Given)
<em>÷3 ÷3 </em>(Get "g" on its own)
g = 10 (30 ÷ 3 = 10)
This is our answer since g = 10 in this equation, and not g = 0 we know that this is our equation.
<em>Just in case, I will do the other options just not as in-depth!</em>
<em />
g + 8 = 8
<em> -8 -8</em>
g = 0
9g = 0
<em>÷9 ÷9</em>
g = 0
Hope this Helps! :)

Answer:
Its the 3 one
Step-by-step explanation:
None because half is 36 which is 11 minutes so 22 minutes would mean nothing is left
