A circle is divided into three arcs of measures x 2x and 3x what’s the value of x

lidiya [134]

Answer:

60°

Step-by-step explanation:

This questions tests our knowledge on arcs and arc measures.

-Arc measure is the angle that an arc makes with the circle's center.

-The arc measure is proportional to the arc.

#The sum of the 3 arcs is x+2x+3x=6x

Given a circle has 360°, the arc measurement x can be calculated as:

$[x+2x+3x]=360\textdegree\\\\6x=360\textdegree\\\\x=60\textdegree$

Hence, the arc measurement x is 60°

What is the reason for each step in the solution of the equation 12-5x+6x=4

djverab [1.8K]

Simplify :
12+-5x+6x=4
combine like terms :
-5x+6x=1x
12+1x=4
solving :
12+1x=4
solving for variable ‘x’
move all terms containing x to the left, all other terms to the right, add ‘-12’ to each side of the equation
12+-12+1x=4+-12
combine like terms:
then divide each side
your answer : x=-8

M<A = m<C = 53
answer is B. 53
-------------
2x = 8
x = 4

answer
D. 4

--------------
y = 3x (1)
y + 12 = 6x so y = 6x - 12 (2)
from (1) and (2) you haev
3x = 6x - 12
3x = 12
x = 4
y = 4x = 4(3) = 12

answer
C. y = 12
