To find the measure of angle 1, you add 33 and 57
That would equal 90 
Since all triangles equal 180, you would subtract 90 from 180 
So the answer would be 90.
        
             
        
        
        
Answer:
A circle is a shape.
Step-by-step explanation:
In geometry circles are known for you to solve the radius wit the formula      A= π r^2
A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.
 
        
             
        
        
        
5x divided by 5
18 divided by 5
X= 18/5 or 3.6
