Answer:
60°
Step-by-step explanation:
Sum of angles of triangle = 180°
x + 40 + 80 = 180
x + 120 = 180 {Subtract 80 from both sides}
x = 180 - 120
x = 60°
Answer: 21
Step-by-step explanation: The amount the gold bar weighs is extra information and is meant to throw you off, 526/24 is 21.9 but because you can’t have a decimal amount of gold bars it’s just 21 in each pot.
21 - 4x = 108
<em><u>Subtract 21 from both sides</u></em>
-4x = 87
<em><u>Divide both sides by -4</u></em>
x = -21.75
