What is the measure of 1

Answer:
92
Step-by-step explanation:
The sum of a quadrilateral interior angles is 360°. In order to get the measurement of the missing angle you have to subtract 360 from 62,92, and 114 which will result in 92
Answer:
∠ 1 = 140°
Step-by-step explanation:
∠ 1 and ∠ 3 are corresponding angles and congruent, thus
30x + 20 = 20x + 60 ( subtract 20x from both sides )
10x + 20 = 60 ( subtract 20 from both sides )
10x = 40 ( divide both sides by 10 )
x = 4
Thus
∠ 1 = 20x + 60 = 20(4) + 60 = 80 + 60 = 140°
