Given
R is the interior of ∠ TUV.
m∠ RUV=30degrees, m∠ TUV=3x+16, and m∠ TUR=x+10.
Find the value of x and the m ∠TUV.
To proof
As given in the question
 m ∠TUV=3x+16, and m ∠TUR=x+10
thus 
m∠ RUV =  m∠ TUV - m∠ TUR
             = 3x + 16 - x -10
             = 2x + 6
As given
m ∠RUV=30°
compare both the values
we get
30 = 2x + 6
24 = 2x
12 = x
put this value in the m ∠TUV= 3x+16
 m ∠TUV= 12× 3 +16
             = 52°
Hence proved
