g. CPCTC (Corresponding parts of congruent triangles are congruent)
Answer
Substitute w by 7
7^3
7x7x7 =343
Exterior angles are complementary to the opposite interior angle
X + 3x + 4x = 56
8x = 56
x = 7
The shortest piece is 7 inches
The middle piece is 7*3 = 21 inches.
The longest piece is 4*7 = 28 inches
Check
7 + 21 + 28 = 56 It does check and the lengths are correct.
7x+2=5(x-2)
7x+2=5x-10
7x-5x=-10-2
2x=-12
x=-6
