Hello,
n=k*z*(x+y)²
with n=18,x=2,y=1 and z=3
==>18=k*3*(2+1)²
==>k=18/27=2/3
x/r - s = t
Add s to both sides.
x/r - s + s = s + t
x/r + 0 = s + t
x/r = s + t
Multiply both sides by r.
r(x/r) = r(s + t)
x = r(s + t)
Understand?
Answer:
25.25
Step-by-step explanation:
Angle Formed by Two Chords= 1/2(SUM of Intercepted Arcs)
The angle formed by the two chords is (180 -x)
We need to find x first
x = 1/2 (54+204)
x = 129
The angle formed by the two chords is (180 -129) = 51
51 = 1/2 ( z+3z+1)
Multiply by 2
102 = 4z+1
101 = 4x
Divide by 4
101/4 = z
25.25 =z
Step-by-step explanation:
24x+72-2
