Given: line ad is congruent line cd; angle 3 is congruent to angle 4prove: line db bisects angle abc

Step-by-step explanation:

Given : AD=CD and

           ∠3=∠4

To prove : Line DB bisects ∠ABC

                i.e.∠ABD=∠CBD

Proof :  Consider ΔABD and ΔCBD,

and

and

So, ΔABD ≅ ΔCBD (By SAS criterion}

Hence , By CPCT (corresponding part of congruent triangle}

∠ABD=∠CBD

Therefore, Line DB bisects ∠ABC.

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
