Answer:
121°
Step-by-step explanation:
The angle with measure x is an exterior angle of the triangle.
The angles measuring 90° and 31° are the remote interior angles to the exterior angle.
<em>Theorem:</em>
<em>In a triangle, the measure of an exterior angle equals the sum of the measures of its remote interior angles.</em>
x = 31 + 90
x = 121°

Answer:
x = 16
Step-by-step explanation:
The probability of obtaining a green ball is
P(green) = 
= 
and
P(green) = 
, hence equating gives
= ( cross- multiply )
2(x + 14) = 60 ( divide both sides by 2 )
x + 14 = 30 ( subtract 14 from both sides )
x = 16
