Question

if cos B equals to 21 upon 29 find the values of tan B Sin B and sec b​

Answer 1

Answer:

Cos B = 21/29

Sin B. = √ 1 - cos²B

Sin B = √ 1 - 441/841

SinB. = √ 400/841

Sin B = 20/29

tan B = sin B / cosB

tan B= 20/29×29/21

tan B = 20/21

Sec B = 1/ cosB

secB = 1× 29/21

secB = 29/ 21
