Not really sure what exactly you are asking, but maybe a bar graph?
Answer: 
Step-by-step explanation:
Given: ∠H ≅∠L and line HJ congruent to Line JL.
Since, In triangles HIJ and LKJ,
∠H ≅ ∠L
HJ ≅ JL
And, ∠HJI ≅ ∠ LJK
Therefore, By ASA postulate,
Δ HIJ ≅ Δ LKJ
This is why Option first is correct.
Note: Option third ΔHIJ≅ΔJKL is not correct,
Because, HI≠JK
If the angles of the triangle are 50, 90, 40 degrees, then only 1 triangle can be made. Because if you change the sides, the angles would change

Answer:A.= (1 - x + y) (1 + x-y)A
B z=3(a - x - y)
C. S = 2/5 y= - 1 z = - 4/5
15 divide 30 by 2 and you have your answer
