Answer:1
1. 
2. ∠ABC = 120°, ∠BCD = 90°, ∠CDA = 60°, ∠DAB = 90°
Step-by-step explanation:
It's important to note here that the measure of all interior angles in a quadrilateral will add up to 360°
We know this using the formula
, a 4 sided figures angles will add up to

This means that all of the angles (4x, 3x, 2x, 3x) will add up to 360.

Combine like terms:

Divide both sides by 12:

We know now substitute x for 30 in for all of the side lengths.
∠ABC = 4x =
°
∠BCD = 3x =
°
∠CDA = 2x =
°
∠DAB = 3x =
°
Hope this helped!
Answer:
12
Step-by-step explanation:

Answer:
12
Step-by-step explanation:
Given:3x+y=6
Value of
6x+2y=12
Since is the result of the equation 3x+y multiply by 2
Answer:
x = 1
Step-by-step explanation:
2x + 8 = 4x + 6
<em>subtract 6 from both sides of the equation</em>
2x + 8 - 6 = 4x + 6 - 6
2x + 2 = 4x
<em>subtract 2x from both sides of the equation</em>
2x - 2x + 2 = 4x - 2x
2 = 4x - 2x
2 = 2x
<em>divide both sides of the equation by 2</em>
2/2 = 2x/2
1 = x
