Answer:

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180 for third angle

third angle = 180° - (39 + 56)° = 180° - 95° = 85° → A

Bill is shopping for folders, notebooks, and pencils for the first day of school. A notebook costs 4 times as much as a folder.

spin [16.1K]

Answer:

$14

Step-by-step explanation:

Assuming the cost of folder to be $x$ , then the cost of notebook will be $4 x$ and the cost of set of pencils will be $2 x$ .

Cost of the folder = $2

Cost of notebook = 4 × 2 = $8

Cost of pencil = 2 × 2 = $4

Total cost of 1 folder, 1 notebook and 1 set of pencils = $2 + $8 + $4 = $14
