Answer:
x=39
y=28
Step-by-step explanation:
this is isosceles triangle
from the picture
angle A equals to angle B
so
34=x-5
39=x
so A and B are 34 degree each
so angle C is 180-2(34)
then 180-2(34)=4y
180-68=4y
112=4y
28=y
Answer:
y=3/2x-16
Step-by-step explanation:
Answer:
A= 4*9
Step-by-step explanation:
A = b*h
A= 4*9
=36
Answer:
B. x=-6 or x=8
Step-by-step explanation:
To solve this, factor the equation x^2-2x-48. Since -48 is negative, one of the factors has to be negative and one has to be positive. Since the coefficient of x is -2, the factors have to sum to -2. Trying factors, we realize that (x-8)(x+6)=0 works. Solving, x-8=0 and x+6=0, or x=8 or x=-6.
Let the point be P, and the masses be located at P1 and P2.
The centre of mass is such that the moments of masses m1 and m2 exert an equal moment at the point P,
and the distance P1P2=d
namely,
m1(mPP1)=m2(mPP2)
The distance of the centre of mass from m1 is therefore
d1=d*m2/(m1+m2)
Similarly, the distance of the centre of mass from m2 is
d2=d*m1/(m1+m2)
