Question

Find x in figure .


Good Answers will be highly appreciated :)​

Answer 1

Answer:

let name given triangle as a b c

b and c are oposite angles

so in triangle ABC

since apposite sides are equal apposite sides also equal

so

=> 12x-18=8x+12

=> 12x-8x=12+18

=> 2x=30

=> x= 30

2

=> x= 15

here is your answer

Answer 2

Step-by-step explanation:

Solution

Given ∠BAC=56  

o

 

∠ACD=123  

o

 [Straight angle]

∴∠ACB=180  

o

−∠ACD=180  

o

−123  

o

=57  

o

 

Consider △ABC,  

By Angle Sum property, i.e, sum of all interior angles of a triangle =180  

o

 

⇒∠A+∠B+∠C=180  

o

 

⇒56  

o

+x+57  

o

=180  

o

 

∴x=67
