Answer:
x = 3 and y = 2
Step-by-step explanation:
For the triangles to be congruent.
The hypotenuse and a leg of one triangle and the hypotenuse and a corresponding leg of the other triangle must be congruent, that is
x = y + 1 → (1) congruent legs
3y = x + 3 → (2) congruent hypotenuse
Substitute x = y + 1 into (2)
3y = y + 1 + 3, that is
3y = y + 4 ( subtract y from both sides )
2y = 4 ( divide both sides by 2 )
y = 2
Substitute y = 2 into (1)
x = 2 + 1 = 3

True
<span>rhombus: opposite angles are equal </span>
4 is again c because you should put the 2 here 2a'2-1 so this is 2a'1 and this is 20 so
A2 is 20
Than you should again do this and find a3 ...
