Mathematics

nlexa [21]3 years ago
3 0

Answer:

The basic idea behind copying a given angle is to use your compass to sort of measure how wide the angle is open; then you create another angle with the same amount of opening.

Step-by-step explanation: these are the steps

Using a straightedge, draw a reference line, if one is not provided.

Place a dot (starting point) on the reference line.

Place the point of the compass on the vertex of the given angle, ∠ABC (vertex at point B).

Stretch the compass to any length that will stay "on" the angle

Angle Pairs Introduction
ra1l [238]

Answer:

  $20.99

Step-by-step explanation:

The sale causes the original price to be multiplied by 1 - 20% = 80%. The tax causes the sale price to be multiplied by 1 + 5% = 105%. The net effect is that the original price is multiplied by the product of these values:

  final cost = $24.99(0.80)(1.05) = $20.99
