If sin 21 = cos (5x+9) what is the value of x
n200080 [17]

sin x = cos 54 = sin (90-54) = sin 46

Hence x = 46 deg

Same technique. Sin 21 = cos (5x+9) = sin (90-5x-9)

81-5x = 21

Or 5x = 60

Or x = 12 deg

hope it helps

What is the equation of the line that passes through (4, 3) and (2, 2)?
anastassius [24]
(4,3)(2,2)
slope = (2 - 3) / (2 - 4) = -1/-2 = 1/2

y = mx + b
slope(m) = 1/2
use either of ur sets of points...(4,3)...x = 4 and y = 3
now we sub and find b, the y int
3 = 1/2(4) + b
3 = 2 + b
3 - 2 = b
1 = b

so ur equation is : y = 1/2x + 1 <==
