Ответ:
The statement is true because :
Both these triangles are Congruent to each under the ASA congruence postulate . We say this because :
1) The two angles in both the triangles which are each other's corresponding part are equal ( 40° = 40° and 50° =50° )
2) There is one common side which is 12 . As both of the common sides are equal , these triangles are said to be congruent to each other .
Ответ:
s² = (s + 5)(0.5s)
The value of s is 5. Thus the dimension of the rectangle in w x h is 2.5 x 10.
