Answer is4/5​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

3cotA=4 (given)

CotA= 4/3

CotA= Base/Perpendicular

i.e. Base= 4x,

Perpendicular= 3x

(Hypotenuse)^2 = (B)^2 + (P)^2

H^2 = (4x)^2 + (3x)^2

H^2 = 16x^2 + 9x^2

H^2 = 25x^2

H = √25x^2

H = 5x

SinB = Perpendicular/Hypotenuse

SinB = 4x/5x (by assuming b as our reference angle, Perpendicular and Base are interchanged)

SinB = 4/5 Ans.....
