Question

choose the correct option .....​

Answer 1

Step-by-step explanation:

1)In quadrilateral ABCD,

LAOC=25°

and LBOC and LBAC=90° each

so sum of all angles in a quadrilateral is 360°

=>90°+90°+25°+LAOC=360°

=>LAOC=360°-205°

=>LAOC=155°

Option D

5) x²-8x+15=0

=>x²-3x-5x+15=0

=>x(x-3)-5(x-3)=0

=>(x-3)(x-5)=0

=>x=3 and 5

Option A

Answer 2

$\large\underline\purple{\bold{Solution :- }}$

$\bf \:\large \red{AηsωeR : 1}$

$\tt\implies \:\tt \:  Option \: (d) \: is \: correct$

$\bf \:\large \red{AηsωeR : 2}$

$\tt\implies \:Option \: (a) \: is \: correct$

$\bf \:\large \red{AηsωeR : 3}$

$\tt\implies \:Option \: (c) \: is \: correct$

$\bf \:\large \red{AηsωeR : 4}$

$\tt\implies \:Option \: (c) \: is \: correct$

$\bf \:\large \red{AηsωeR : 5}$

$\tt\implies \:Option \: (a) \: is \: correct$
