Answer:
37°
Step-by-step explanation:
As we know the sum of angles of a triangle is 180  degrees.
Therefore, 
angle A + angle B + angle C = 180°
In the given picture two angles are given and we have to find out the third angle. 
x° + 45° + 98° = 180°
x° + 143° = 180°
x° = 180° - 143°
x° = 37°
The value of x in the triangle shown is 37°.
 
        
             
        
        
        
sqrt (3/10)
sqrt(3)/sqrt(10)
no sqrt in the denominator, so multiply by sqrt(10)/sqrt(1)
sqrt(3) sqrt(10)
-------------------
sqrt(10) sqrt(10)
sqrt(30)/10
