Option C is needed because the reason for proving this pair of congruent triangles is SAS, (an angle between 2 equal sides)
Answer:
h=9cm
P=(x+5)cm
b=(x-3)cm
by the Pythagoras theorem,
h^2=p^2+b^2
9^2=(x+5)^2+(x-3)^2
81=x^2+10x+25+x^2-6x+9
81=2x^2+4x+34
Step-by-step explanation:
By AAS congruence, triangles RNM and RNP are congruent. Hence 7x = 2x + 25, x = 5.
Line RM = 7x = 7(5) = 35 units.
Answer:
The probability is "0.6406", this elevator isn't appear to be safe
Step-by-step explanation:
The given values are:
Mean,

Standard deviation,

Number of male passengers,

Now,
⇒ 

hence,
The probability will be:
= 
= 
=
The Answer would be 4x= 75+25 4x= 100 x= 100/4 x=25
