Abbey is flying a model plane. she releases the plane and it flies a distance of 55 meters, then makes a 130° turn and flies a distance of 35 meters before it lands. the map below, shows the path of the plane. the letter x marks the spot where the plane started and y marks the spot where the plane landed.
use the law of cosines to determine the distance, in meters, between where the model plane lands and where it started from.
enter this distance, rounded to the nearest meter.

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

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
