This one is a tough one. If you can explain it to me that’ll me great.
A. 78
B.84
C.73
D.79

Answer:
C. 73 if I have read the given angle measurements correctly.
The angle measurements I see are:
[tex]219^\circ[/tex]
[tex](x-50)^\circ[/tex]
[tex](x+45)^\circ[/tex].
Step-by-step explanation:
Those angles together form a full rotation. A full rotation is equal to 360 degrees.
So we have the following equation to solve:
[tex]219+(x-50)+(x+45)=360[/tex]
Combine like terms:
[tex](x+x)+(219-50+45)=360[/tex]
Simplify:
[tex]2x+(219-5)=360[/tex]
[tex]2x+214=360[/tex]
Divide both sides be 2:
[tex]x+107=180[/tex]
Subtract 107 on both sides:
[tex]x=180-107[/tex]
[tex]x=73[/tex]
Answer:
C) 73
Step-by-step explanation:
360-219=141
(x-50)+(x+45)=141
2x-50+45=141
2x-5=141
2x=141+5
2x=146
x=146/2
x=73
