Find the measure of angle x in the figure.
1 answer:
Answer:
8
Step-by-step explanation:
We know that angles in a triangle add up to 180, so:
5x-60+2x+40+3x-80=180
Simplify
10x-100=180
Solve
<em>Subtract </em><em>100 </em><em>from </em><em>both </em>sides
10x=80
<em>Divide</em><em> </em><em>8</em><em>0</em><em> </em><em>by </em><em>1</em><em>0</em><em> </em><em>to </em><em>find </em><em>x</em>
x=8

Your answer is going to be 13.151
2x - 3y = - 2
3x - 2y = 12
the value of X in the solution to the system is 4.
