Answer:
∠A = ∠D (**but very important Δ ABC has to be congruent to Δ DEF)
Step-by-step explanation:
It will help if you draw the triangles out and label the same sides. Then according to the side-angle-side (SAS) rule, ∠A should be equal to ∠D

The probability of getting an even number is 1/2 on each throw. So getting an even number on all three throws is 1/23=1/8.
From 2009 to 2017 energy has changed because in 2009 windmills were used and such things and in 2017 modern energy has been created
Answer:
2
Step-by-step explanation:
2 is the constant of proportionality in the equation y = 2x . When two variables are directly proportional to each others . Where k is called the constant of proportionality . Thus in the question x and y are proportional variables
