Answer:
31
Step-by-step explanation:
sum of the bordering angles is 180° so
(5x-16) + (x+10) = 180
5x - 16 + x + 10 = 180
6x - 6 = 180
6x = 186
x = 186 ÷ 6
x = 31
Answer:
The answer is x=31.
5x-16+x+10=180
6x-6=180
6x=186
x=31
Then, 5(31)-16=
155-16= 139
Also, x+10=
31+10=41
Solution check:
139+41=180, so x=31 is correct.
