given triangle ABC with MB equals 62 degrees and side AC extended to d as shown below which value of x makes a b congruent to CB
disa [49]
4) 121 degrees 
because if x is 121 degrees then angle BCA will equal 59 degrees (the two angles must equal 180) so using the sum of a triangle's angles, then angle BAC will have to equal 59, making the triangle an isoceles, which will make AB to be congruent to BC.

Find the value of x. Select one: a. 2.3 inches b. 3.3 inches c. 4.1 inches d. 6.1 inches
spayn [35]

Answer:

c 4.1 inches

Step-by-step explanation:

The circumference of a circle is given by

C = 2*pi*r

The sector is only 78 degrees

Take the fraction of a circle  and multiply by the circumference to find the length x

x = C* 78/360

  = 2 * pi *r * 78/360

  = 2 * pi *3 * 78/360

Using 3.14 for pi

  = 4.082

Rounding to the nearest tenth

x = 4.1 inches
