Answer:
if x=2, y= 1
if x=5, y=-5
Step-by-step explanation:
6x+3y=15
3y=-6x+15
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
y=-2(5)+5
y=-10+5
y=-5
Given:
Figure of similar triangles.
To find:
The value of x and the measure of NR.
Solution:
In triangle RST and RMN,
(Vertically opposite angles)
(Alternate interior angles)
(By AA property of similarity)
We know that, corresponding sides of similar triangles are proportional.
On further simplification, we get
The value of x is 7.
Now,
Therefore, the value of x is 7 and the measure of NR is 12 units.
Answer:
Use pythagoreum theorem to determine whether it is or isn't since I'm not really sure myself but here's my calculations.
Step-by-step explanation:
We need to find AC.
Picture a triangle called ABC. AB is one side and BC the other while AC is the hypotenuse.
AC=
Round up the 7.6 to a whole number and you get AC=8. To get perimeter of a triangle simply add the sides together to get 18.
Not really sure about my answer but hope this helped.
