Please help I don’t understand

Line m and n are parallel lines that are intersected by a line

This means that corresponding angles in each line are equal to each other

This means that angle (3x+58) is equal to (5x)

now, we can solve for x and from there find the angle measure

(3x+58)=5x

3x-3x+58=5x-3x

58=2x

58/2=2x/2

29=x

if 29=x then 5(29)=5x

the angle measure of these angles is 145

Step-by-step explanation:

Step-by-step explanation:

m // n  and they are intersected by transversal.

Corresponding angles are equal

5x = 3x + 58

5x - 3x = 58

     2x = 58

      x = 58/2

x = 29

i think the length is 12 and the width is 17

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
