Question

Given: OP ×OS =OR ×OQ
To prove:

Answer 1

Answer:

Question:−

1−sin(α)

cos(α)

=

cos(α)

1+sin(α)

Answer:−

LHS:−

=

1−sinα

cosα

=

1−sinα×(1+sinα)

cosα×(1+sinα

=

(1−sin

2

α)

cosα(1+sinα)

=

cos

2

α

cosα

+(1+sinα)

=

cosα

1+sinα

=RHS.

Answer 2

Answer:

your answers is

Step-by-step explanation:

angle P = angle R

angleQ = angle S

{given }

angle poq= angle ros

{VOA }

SO BY ASA SIMILARITY ∆POQ ~ ∆ROS

PO / OR = OQ / OS

PO×OS = OR × OQ

ANS = RHS

{QED}
