Answer:
x  ≈ 10.7 ft.
Step-by-step explanation:
Given triangle in the picture is a right triangle. 
By applying Pythagoras Theorem in this triangle.
(Hypotenuse)² = (Leg 1)² + (Leg2)²
(14)² = x² + 9²
x² = (14)² - 9²


x = 10.72
x  ≈ 10.7 ft.
 
        
             
        
        
        
Answer:
32+78+x=180
Step-by-step explanation:
All triangle angles add up to 180, so add 78 and 32 then subtract it from 180 to get x, which in another form is 32+78+x=180.
