Question

If A + B = 90°sinA 3 / 4 then secB is *


​

Answer 1

Answer:here is the answer

Step-by-step explanation:

SinA=3/4

Sin (90-B)=3/4. ......given A+B=90

CosB= 3/4

Now reciprocol

secB =4/3

Answer 2

Answer:

sec B=4/3

Step-by-step explanation:

A+B=90

A=90-B

sinA=3/4

sin(90-B)=3/4

cosB=3/4

secB=4/3
