Please answer this question​

Answer 1

Answer:

A+B+C=180°

∴A+B=180-90

∴A+B=90

∴sec(90)=not defined

Answer 2

Answer:

Not defined

Step-by-step explanation:

We know that angle c is 90 degree

Using angle sum, ie  angle a+b+c = 180, we will get

Angle a +angle b =180-angle c

Angle a +angle b=180-90 =90

Therefore sec (A+B)=sec (90)

the value of sec 90 is not defined
