Answer:
56
Step-by-step explanation:
Missing length = x + 21
Based on the Three Parallel Lines Theorem, we have:
x/21 = 20/12
Cross multiply
x*12 = 20*21
12x = 420
12x/12 = 420/12
x = 35
✅Missing length = x + 21
Plug in the value of x
= 35 + 21
= 56
Answer:
4 root 5
Step-by-step explanation:
assume / to be root sign
/10 x /8
simply both roots so that one of numbers is a square number
/10= /2 x /5
/8= /2 x /4
so
/4=2 and /2 x /2= 2
2×2=4 and you have /5 left over so
4/5
hope this helps!
So you gave yourself the own answer lol
The findings 20/40 vision in the right eye implies that when Tina is standing at a distance of 20 feet away from the eye chart, she will be able to read with her right eye what a person with normal vision can read from a distance of 40 feet away from the eye chart. Also, Tina has got 20/20 vision in the left eye, this implies that when Tina stands 20 feet from the eye chart , she will be able to read with her left eye what a person with normal vision can read from 20 feet away with the left eye. In conclusion this implies that Tina has normal vision in her left eye but a decreased vision in her right eye.
