If 2 angels are consecutive interior angles of the parallel lines and the measure of one is (4x - 2) and the other is (5x - 7). Find the measure of the first angle

The lengths in cm of three sides of a triangle are three consecutive odd numbers.
Knowing that the perimeter of the triangle is 40.5 dm, find the length of the longest side of the
triangle.
A.137cm
B.135cm
C.143cm
D.145cm
 

In triangle ABC the points D and E are the intersections of the angular bisectors from C and B with the sides AB and AC respectively. Points F and G on the extentions of AB and AC beyond B and C respectively, satisfy BF= CG= BC. Prove that FG//DE.

The lengths in cm of three sides of a triangle are three consecutive odd numbers. Knowing that the perimeter of the triangle is 39cm, find the length of the longest side of the triangle. Show your work.

Fill in the circles with the numbers 1, 2, 3, 4, 5, 6 and 7. Each number can be used once without repetitions. The sum of the digits inside the circles at the four vertices of the square on the left is 15 and the sum of the digits inside the circles at the vertices of the regular pentagon on the right is 24. How many possible arrangements are there?

If 2 angles are consecutive interior angles of the parallel lines and the measure of one is(4x-2)^o and the other is (5x-7)^o.The measure of the first angle is...^o.
