What is the length of bc ? 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 2 x minus 24. the length of side a b is labeled as x minus 2. the length of side b c is labeled as x.

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal interior angles

In this problem

Triangle ABC is an isosceles triangle

because

∠B≅∠C

therefore

AB=AC

substitute the values

Solve for x

Find the length of side BC

substitute the value of x

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
