What is the length of side bc of the triangle? enter your answer in the box. units triangle a b c with horizontal side b c. vertex a lies above side b c. angle b and angle c are marked congruent. the length of side a c is labeled as x plus 8. the length of side a b is labeled as 2 x minus 1. the length of side b c is labeled as 3 x minus 3.

 Length of BC = 24 units.

Explanation:

Given that in triangle ABC, BC is the base, and angle B = angle C

SInce two angles are equal, ABC is isosceles with sides AB = AC

Given that AC = x+8 and AB = 2x-1

Since AB = AC we get these two are equal.  Use this t solve for x.

x+8 = 2x-1

x =9.

It is easy to find BC now.

BC =3x-3

Hence BC =3(9)-3 = 24

Length of BC= 24 units.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
