Answer 1

HEY MATE,LET ME HELP YOU WITH YOUR QUERY!

I AM HELPING IN THE QUESTION 7,AS IT SEEMS A LITTLE BIT TRICKY!

7.Given A+B=45

 {Take tan on both the sides }

tan(A+B) = tan45

tanA+tanB/1- tanA tanB = 1

tanA+tanB=1-tanA.tanB

tanA+tanB+tanA.tanB=1

adding "1" on both sides

1+ tanA+tanB+tanA.tanB=1+1

(1 + tanA)+tanB(1+tanA).=2

(1+tanA)(1+tanB)=2   Hence proved .

HOPE YOU ARE REALLY HELPED MATE...PLEASE CONSIDER MARKING MY ANSWER AS BRAINLIEST...
