Answer:

from \: snell {}^{.} s \: law : \\  n =  \frac{ \sin(i) }{ \sin(r) }  \\  \sqrt{3}  =  \frac{ \sin(i) }{ \sin(30 \degree) }  \\  \sin(i)  =  \sqrt{3}  \times  \sin(30 \degree)  \\  \sin(i)  = 0.866 \\ i =  { \sin}^{ -1 } (0.866) \\ i = 60 \degree

Find the solution set of x + y = 5, 2 x - y = 7
STALIN [3.7K]
X + y = 5
x = 5 - y

2x - y = 7
2(5-y) - y = 7
10 - 2y - y = 7
10 - 3y = 7
10 - 7 = 3y
3 = 3y
y = 1

x + y = 5
x + 1 = 5
x = 5 - 1
x = 4
