Answer:

x = 127°

Step-by-step explanation:

Let A, B and C be the three angles of a quadrilateral such that they are 55, 73, 105 respectively.

We know that, the sum of angles of a quadrilateral is equal to 360°. Let fourth angle be x.

55+73+105+x = 360

233+x=360

x = 360-233

x = 127°

So, the fourth angle is equal to 127°.

2x – 3 &gt; -4x + 2<br> What is the solution to the inequality
bagirrra123 [75]

Answer:

x>\frac{5}{6}

Step-by-step explanation:

2x-3>-4x+2

Add 3 to both sides

2x-3+3>-4x+2+3

Simplify

2x>-4x+5

Add 4x to both sides

2x+4x>-4x+5+4x

Simplify

6x>5

Divide both sides by 6

\frac{6x}{6} >\frac{5}{6}

Simplify

x>\frac{5}{6}
