Answer:

x = 27

Step-by-step explanation:

Since AC and DE are parallel lines, then

∠ BAD = ∠ EDF= 2x ( corresponding angles )

The sum of the 3 angles in Δ BAD = 180°, thus

2x + 2x + 72 = 180, that is

4x + 72 = 180 ( subtract 72 from both sides )

4x = 108 ( divide both sides by 4 )

x = 27

  • h = 433

Step-by-step explanation:

Using the problem statement as the basis for the equation, we can write ...

  h -102 = 331

__

Using the diagram as the basis for the equation, we could write it as ...

  h = 331 +102

How many solutions does 10+5x=5x+10 have?
Arturiano [62]
Simplifying
10 + 5x = 5x + 10

Reorder the terms:
10 + 5x = 10 + 5x

Add '-10' to each side of the equation.
10 + -10 + 5x = 10 + -10 + 5x

Combine like terms: 10 + -10 = 0
0 + 5x = 10 + -10 + 5x
5x = 10 + -10 + 5x

Combine like terms: 10 + -10 = 0
5x = 0 + 5x
5x = 5x

Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x

Combine like terms: 5x + -5x = 0
0 = 5x + -5x

Combine like terms: 5x + -5x = 0
0 = 0

Solving
0 = 0

HELP NEEDED ASAP WILL GIVE 5 STAR RATING AND BRAINLIEST!

Answer:

The answer to your question is: ∠K   = 138°

Step-by-step explanation:

m∠N = 42°

m∠K = ?

The sum of all the internal angles in a quadrangle equals 360°

then

        ∠N + ∠L + ∠M + ∠K = 360°

        ∠N = ∠ L   and ∠M = ∠K

So, 2 ∠N + 2 ∠K = 360

Substitution

       2 (42) + 2 ∠K = 360

       84  + 2 ∠K = 360

       2 ∠K = 360 - 84

       2 ∠K = 276

      ∠K  = 276 / 2

     ∠K   = 138°

Ok guys my friend is telling me that i am doing this problem wrong 4^4+1/2=256.5 and he is tell me that it is 16.5 am i right or
Alexxx [7]

Simplify 4^4 to 256

256 + 1/2 = 256.5

Simplify 256 + 1/2 to 513/2

513/2 = 256.5

Since both sides equal, there are infinitely many solutions.
