Answer:
11y + 2x + 12
Step-by-step explanation:
put similar numbers together:
1. 7y + 4y = 11y
2. 8 + 4 = 12
3. 2x has no match so it is left alone
Put the numbers back together into a new equation: 11y + 2x + 12
Convert to base 10
2×3² + 0×3¹ + 1×3^0 = 18 + 0 +1 = 19 base 10
so convert 19 to base 8
19 base 10 = 23 base 8

Answer:
x = 125°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for x, that is
x = 180° - (30 + 25)° = 180° - 55° = 125°
