Question

In ∆ABC (see figure) <C = 90°,
AB = x units and AC = 3 units.
EVALUATE :
xcosB×tanA + x^2sinA×secB + sinC​

Answer 1

Answer:

12+2√2

Step-by-step explanation:

Firstly by assuming that its an isosceles triangle... We'll get all its sided as x=3√2 and the third one is 3..

After that claculate all the valuse of the given eq.

Then put it according to x and the other two sides..

After this you'll get an irrational fractional digit..

Which is.. :

(36√2+12)/3√2

Nad after rationalising it.. We'll get...

12+2√2...
