You are correct @Ashwini.

Sin θ =opposite side/hypotenuse sin(theera) = AB/ AC.
AB=Ac sin45. = 10 sin45= 10 * 0.707.
So, AB = 7.07.
AB=Ac sin45. = 10 sin45= 10 * 0.707.
So, AB = 7.07.

Sin 45 = AB/10.
0.707 * 10 = AB.
AB = 7.07.
0.707 * 10 = AB.
AB = 7.07.

Sine45 degree = AB\10.
AB = 7.07 => Answer.
AB = 7.07 => Answer.

AB = Perpendicular; AC = hypotenuse.
Now we know sin 45 = AB/AC.
->> 1/sqrt2 = AB/10.
->> 0.707 = AB/10 (1/sqrt2 = 0.707).
->> AB = 10*0.707.
->> AB = 7.07.
Now we know sin 45 = AB/AC.
->> 1/sqrt2 = AB/10.
->> 0.707 = AB/10 (1/sqrt2 = 0.707).
->> AB = 10*0.707.
->> AB = 7.07.

Without calculator how will you find out sin 45 is 0.707. Did you use any tricks?

sin 45 = ab/10.
(sin 45 = 0.07)
ab = .07x10.
ab = 7.07.
(sin 45 = 0.07)
ab = .07x10.
ab = 7.07.

Sin45 = AB/10.
0 = AB/10.
AB = 7.07.
0 = AB/10.
AB = 7.07.

Sin 45 = AB/10.
0.707*10 = AB.
AB = 7.07.
0.707*10 = AB.
AB = 7.07.
