Answer:
For every pound that the package weight increases, the price of sending it increases by $3.80.
Step-by-step explanation:
The coefficient 3.80 multiplies the variable x (package weight), so if x is 1 pound the cost increase $3.80, if x is 2 pound the cost increase 2*3.80 = $7.6, and so on. Generally speaking, for every pound that the package weight increases the cost increases by $3.80.
Answer:
None of these lines are parallel, so the congruent angles are vertical angles. 4 and 2 are vertical, thus they are congruent.
Step-by-step explanation:
Right triangles. It allows one to find the length of the sides of a triangle given the degree of its angles. It can also be used to find the degrees of its angle given the length of two of its sides.
Answer:
SSS
Step-by-step explanation:
Two triangles are said to be congruent if all their three sides are equal and all of their three angles are equal. There are 5 ways of determining congruent triangle which are:
- SSS (side, side, side): This is when the two triangles have all three sides equal to each other.
- SAS (side, angle, side): This is when the two triangles have 2 equal sides and one included angle of both triangles are equal.
- ASA (angle, side, angle): This is when the two triangles have 2 equal angles and one included side of both triangles are equal.
- AAS (angle, angle, side): This is when the two triangles have 2 equal angles and one non included side of both triangles are equal.
- HL (hypotenuse, leg): The hypotenuse is the longest leg of a right angled triangle. If two triangles have equal hypotenuse and one equal leg, they are congruent.
Triangle ABC and triangle BCD are congruent because:
AB = CD, AC = BD and both triangles share the same side BC. That is they have three equal sides (SSS)
