3.) A map is made of a park. The scale from the park to the map is 6 mi. to 1 cm. The length of Great Oaks Trail is 4.5 cm on this map. The scale from the same park to a different map is 8 mi. to 1 cm. The length of Salamander Trail is 3.5 cm on that map. Which is the longer trail, the Great Oaks Trail or the Salamander Trail? Great Oaks Trail (the scale is 6 mi. To 1 cm.)
The length of Great Oaks Trail is 4.5 cm. on the map. What is the actual length?

Salamander Trail (the scale is 8 mi. To 1 cm.)
The length of Salamander Trail is 3.5 cm. on the map. What is the actual length?

Which trail is actually longer?

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
