Question

This one is a tough one. If you can explain it to me that’ll me great.

Answer 1

Answer:

C. 73 if I have read the given angle measurements correctly.

The angle measurements I see are:

$219^\circ$

$(x-50)^\circ$

$(x+45)^\circ$.

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:

$219+(x-50)+(x+45)=360$

Combine like terms:

$(x+x)+(219-50+45)=360$

Simplify:

$2x+(219-5)=360$

$2x+214=360$

Divide both sides be 2:

$x+107=180$

Subtract 107 on both sides:

$x=180-107$

$x=73$

Answer 2

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
