THEOREM:
- Angle sum property —: The sum of interior angles of a triangle is 180°.
ANSWER:
Let the missing angle be x.
By angle sum property,
- ∠x + 20° + 80° = 180°
- ∠x + 100 = 180°
- ∠x = 180° – 100°
- ∠x = 80°
So, <u>Correct choice</u> - [C] 80°.

Answer:

$124 higher
Step-by-step explanation:
Given


Required
Represent the situation
Determine how much higher or lower is the remaining amount
Let the initial amount in his account be represented with x
When he deposited, the balance becomes

When he withdrew, the balance becomes

Hence, the algebraic expression is

Calculating how much higher or lower

Open bracket


Recall that the initial amount in the account is x
The difference between the balance and the x is as follows


<em>Hence, the account has a higher of $124 after both transactions</em>
