Answer:
1). x° + 100° + 120° + 100° = 360°
2). x = 40
Step-by-step explanation:
Formula for the sum of the interior angles of a polygon =
Where n = number of sides of the polygon
From the picture attached,
For n = 4,
Sum of the interior angles of the given polygon = (4 - 2) × 180°
= 360°
Therefore, equation for the sum of interior angles will be,
x° + 100° + 120° + 100° = 360°
x° + 320° = 360°
x° = 360° - 320°
x° = 40°
Answer:
The loan amount of the tuition fee is $3285
Step-by-step explanation:
Given as :
The student's tuition fee amount = $2628
The loan amount for the fee = of the tuition fee
Let The loan amount = $ A
So, According to question
The loan amount for the fee = × tuition fee amount
A = × $2628
or, A =
Or, A = 5 × 657
∴ A = $3285
So, The loan amount = A = $3285
Hence The loan amount of the tuition fee is $3285 Answer
