Answer:
x = 63
Step-by-step explanation:
The sum of the angles of a triangle is 180
71+46+x = 180
Combine like terms
117+x =180
Subtract 117
117+x-117= 180-117
x =63
[tex]63 \: \: degrees[/tex]
[tex]46 + 71 + x = 180 \\11 7 + x = 180 \\ x = 180 - 117 \\ x = 63[/tex]
Sum of the interior angles in a triangle is equal to 180 degrees
