Angle 1 and 4 are alternate interior angles
angle 2 and 3 are corresponding angles
angle 3 and 4 are vertical angles
angle 4 and 6 are same side interior angles
Answer:
x = 6, y = 5
Step-by-step explanation:
When x = 6 and y = 5,
3(6) - 5 = 13
18 - 5 = 13
13 = 13
L.H.S = R.H.S
20 x 42= 840
So the area would be 840 mm^2.
