Which statement is true about angles 3 and 5?
Y_Kistochka [10]

The correct statement which is true about angle 3 and 5 is, they are supplementary.

Step-by-step explanation:

  • Two parallel lines are intersected by a third line so that  angles 1 and 5 are congruent as they are supplementary.
  • Supplementary Angles  are Supplementary when the two angles are add up to 180 degrees.
  • Examples of supplementary angles are 60° and 120°.
  • Two lines are parallel when their slopes are equal. In order to see if the two lines are parallel, we must compare their slopes.
  • A transversal is also known as a line segment, that intersects two or more other lines or also a line segments. When a transversal intersects parallel lines many angles are formed, which are known as congruent.
  • If two parallel lines are intersected by a transversal, the corresponding angles are congruent.
  • If two lines are intersected by a transversal,  the corresponding angles are called as congruent i.e the lines are parallel.

A total of 300 trees will be planted in a park. There will be 2 pine trees planted for every 3 maple trees planted. Plot the poi
Pie
Here are the steps: pt= pine treed mt= maple trees t=trees

2 pt + 3 mt = 5 t
So 300 trees divided by 5 trees gives you 60
300 trees / 5 trees = 300 / 5 = 60
To find the amount of pine trees multiply 60 by 2 which is 120
To find the amount of maple trees multiply 3 by 60 to get 180
So the answer to your question is 120 pt and 180 mt
