What is the value for y? Enter your answer in the box. y = An isosceles triangle A B C with horizontal base A B and vertex C is below the base. Side A C and C B are labeled with single tick mark. All the three angles are labeled. Base angles C A B is labeled as 34 degrees and angle C B A is labeled as left parenthesis x minus 5 right parenthesis degrees. The angle A C B is labeled as 4y degrees.

Answer:

y=28

Step-by-step explanation:

an isosceles triangle's base angles are congruent.

This means that both base angles will be 34 degrees.

to figure out the value of x, we have to say "what minus 5 equals 34?"It would be 39 because 39-5=34.

To find the value of y, we need to fugure out how many degree angle C is.

    1) all triangles are 180 degrees. so, 34+34+angleC=180

    2) 34+34=68

    3)180-68=112

    4) 4y=112

    5) divide both sides by 4.

    6) y=28 because 28·4=112
