Hey there!
ASSUMING
(3x)° + 45° = 180°
3x + 45 = 180°
SUBTRACT 45 to BOTH SIDES
3x + 45 - 45 = 180 - 45
SIMPLIFY IT!
3x = 180 - 45
3x = 135
DIVIDE 3 to BOTH SIDES
3x/3 = 135/3
SIMPLIFY IT!
x = 45°
Therefore, the answer should be:
x = 45
Good luck on your assignment & enjoy your day!

Answer:
1. -42
2. 42
3.42
Step-by-step explanation:
you do is just put the sum in the calculator and u will find your answer hope it helps
3x3 + 4(3x2)/2
9 + 12
21 in^2
5(700)+(50)+(4)that’s how you write it
8 divided by 12 times 30 = 20.
A quicker way is to realise 12 and 30 are multiples of 6. So you can divide 8 by 2 (4) and multiply by 5 = 20.
