Step-by-step explanation:
The perpendicular bisector of a line segment
open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.
Call the two points where these two arcs meet C and D. Draw the line between C and D.
CD is the perpendicular bisector of the line segment AB. Call the point where CD intersects AB E.
Proof. top.
Answer:
z=2
Step-by-step explanation:
5/20=z/8
Rewrite the equation as z/8=5/20
z/8=5/20
Multiply both sides of the equation by 8.
8⋅z8=8⋅520
Simplify both sides of the equation.
z=2

Answer:
a : b : c = 12 : 10 : 15
Step-by-step explanation:
Given that: b = 
of c
i.e b = 
............... 1
2c = 5b
So that;
c = 
.................... 2
Also,
4a = 3c
a = 
................ 3
⇒ a = 
× ()
a = 
................. 4
15b = 8a
b = 
................. 5
Comparing the derived equations:
From equations 2 and 3,
a:c = : = 4:5
From equations 1 and 2,
b:c = : = 2:3
But a common value of b = 15, gives;
a : c = 12 : 15 and b : c = 10 : 15
Thus, a : b : c = 12 : 10 : 15
