Question

plz answer it as fast as u can




sample paper maths ​

Answer 1

Answer:

Step-by-step explanation:

SinA = 1/2, CosB = 1

SinA = 1/2 = Sin30°  => A = 30°

CosB = 1 = Cos0° = B = 0°

CosA = Cos30° = √3/2

SinB = SIn0° = 0

Cosec(A+B) = 1/Sin(A+B)

Sin(A+B) = SinACosB + CosASinB

              = 1/2 * 1 + √3/2 * 0 = 1/2

=> Cosec(A+B) = 1/(1/2) = 2.

Answer 2

Answer:

answer is 2

Step-by-step explanation:

so sinA= 1/2

means A= 30°

and cosB=1

means B= 0°

so Cosec(A+B) = cosec(30°+0°)

= cosec30°

= 2

hope it helped :)
