Answer:
AC = 25 units
Step-by-step explanation:
Given ∠ A = ∠ C then the triangle is isosceles and BC = AB , that is
7x - 1 = 5x + 5 ( subtract 5x from both sides )
2x - 1 = 5 ( add 1 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Then
AC = 6x + 7 = 6(3) + 7 = 18 + 7 = 25 units
The explanation is here. the rest of the questions must be do by yourself.
Answer:
JM = 10
Step-by-step explanation:
Because MN║JL,
=
2(5) = 1(2x + 4)
10 = 2x + 4
2x = 6
x = 3
JM = 2x + 4 = 2(3) + 4 = 6 + 4 = 10
