Answer 1

Answer:

see below

Step-by-step explanation:

125  

o

+∠BAC=180  

o

 

∴∠BAC=55  

o

 

Sum of all angles of a triangle is 180  

o

.

x+90  

o

+∠BAC=180  

o

 

x=180  

o

−90  

o

−55  

o

 

∴x=35  

o

 

OR

Since, Exterior angle= Sum of interior opposite angles, therefore x+90  

o

=125  

o

 

⇒x=120  

o

−90  

o

=35
