Answer:
NR = 12
Step-by-step explanation:
Given that both trjangles are similar, therefore, it follows that their corresponding side lengths would be proportional to each other. Thus:


Cross multiply


(addition property of equality)

Divide both sides by 10
x = 7
✔️NR = 2x - 2
Plug in the value of x
NR = 2(7) - 2 = 14 - 2
NR = 12
Answer:
yes
Step-by-step explanation:
x=3-y
2(3-y)+7y=16
6-2y+7y=16
5y=10
y=2
x=3-2=1
