It’s going to be B. 50+60+70=180 which is how many degrees are in a triangle.
        
                    
             
        
        
        
Answer:
the  height is :  2365.48  m 
Step-by-step explanation:
hello : 
h(t) = − 4.9 t 2 + 211 t + 94 .
the vertex of this parabola is : (-b/2a  , h(-b/2a) when : a= -4.9  and b=211
-b/2a = -(211)/2(-4.9) = 21.53
h(21.53) = -4.9(21.53)²+211(21.53)+94 = 2365.48  m 
 
        
             
        
        
        
Answer:
(23,-4): units
 units 
Step-by-step explanation:
We are given that M(-19,4)and P(4,0)
We have to find the ordered pair that represents MP and find the magnitude of MP.
MP=P-M
MP=(4,0)-(-19,4)=(4+19,0-4)
MP=(23,-4)
Magnitude of MP=
Magnitude of MP=
Magnitude of MP= units

Answer:
180°
Step-by-step explanation:
∠LMN = 90° and is the angle in a semicircle, thus
LN is the diameter of the circle and the measure of arc LPN is
m arc LPN = 180°
