Answer 1

Answer:

please substitute you given part in the to prove part u will get your answer

Answer 2

Answer:

Given, SinA = 1

SinA = 1/1

We know that SinΦ = P/H

( Perpendicular upon Hypotenuse )

By pythagoras theorem we get,

P² + B² = H²

B = √ H² - P²

B = √ 1 - 1

B = √0

B = 0

Now we know that,

CosΦ = B/H

Therefore, CosA = 0/1 = 0

Now we have to solve the following :-

SinA - 5 CosA

Put the values of SinA and CosA from above

1/1 - 5 ( 0 )

= 1 - 0

= 1
