Step-by-step explanation:
the sum of angels of a triangle is 180°
130+ ? + (180-160) = 180

Answer:
15
Step-by-step explanation:
we need to write the equation. I came up with....
3(5 - x) = 30
so take the 3 away from the 30. I think your not supose to do the 3 because it out of the ( ). the opppisite of multiplication is division. so...
3 divided by 30 =10
rewrite
(5 - x) = 10
take the 5 away. the oppisite of subbtraction is addition.
5 + 10 = 15
check your; plug in x
3(5 - 15) = 30 This equation looks true!
Hope this helped! Please mark as brainliest! Thanks
