68= 4x-2+30 (notice they are vertical angles)
68= 4x+28
40=4x
10=x
68+y= 180 (forms a straight angle)
y=112
Final answer: x=10, y=112
Answer:
Porpotional
Step-by-step explanation:
because it is non proportional
well, if we try to plot and conect them, we will get square, so the answer is d
Length＝x
Breadth＝1/3x
(x＋1/3x)×2＝80
4/3x×2＝80
8/3x＝80
x＝30
Length＝30
Breadth＝1/3×30＝10
Hope my answer helped u :)
