Given:
angle ECB=51 degrees
=>
angle EOB = 2*angle ECB = 2*51 = 102 degrees = arc EAB
Also given minor arc AB = 72 degrees
therefore
minor arc EA = 102-72=30 degrees
Answer:
Step-by-step explanation:
equilateral triangle
The value of x - coordinate is 14.4
<em><u>Solution:</u></em>
Given that we have to find the x -coordinate of the system
<em><u>Given system of equations are:</u></em>
2x + 3y = 144 -------- eqn 1
y - x = 24 --------- eqn 2
Solve the above system of equations to find the x - coordinate
From eqn 2,
y = 24 + x ------- eqn 3
Substitute eqn 3 in eqn 1
2x + 3(24 + x) = 144
2x + 72 + 3x = 144
Add the like terms
5x + 72 = 144
5x = 144 - 72
5x = 72
Divide 72 by 5
x = 14.4
Thus the x - coordinate of the system is 14.4
You gotta show the picture or else we cant answer sorry :(
