Answer:
The value of a is 50°.
Step-by-step explanation:
In an isosceles triangle, 2 sides have the same lengths and same angles so we can assume that the other side of the triangle is 65°. 
Given that the total angle of a triangle is 180°, so have to subtract it :



 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Slope = (y2 -y1)/(x2-x1)
y2 = 800, y1 = 400, x2= 4, x1= 2
Slope = (800-400)/(4-2)
= 400/2
