Answer 1

$\huge\tt\underline\pink{ÅŇŚWĘŘ}</p><p>$

Assertion (A):cos1<cos2

1=57⁰

2=2(57)=114⁰

cos57⁰>cos114⁰

reason(R): In (0,π) cosx is decreasing function.

so,A is false and R is true.

Answer 2

$\huge\tt\underline\red{ANSWER}$

$\huge\tt\underline\pink{ASSERTION COS1<COS2}$

$\huge\fbox\red{ 1=57⁰}$

$\huge\fbox\pink{ 2=2(57)=114⁰}$

$\huge\colorbox{CYAN}{REASON (0,π)COSX IS DECREASING FUNCTION}$

$\huge\colorbox{LIME}{ASSERTION IS FALSE REASON IS TRUE}$
