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

<h2>
23</h2>
Step-by-step explanation:
29 is 6 more than K
Let's create an equation
Move variable to L.H.S and change its sign
Similarly, move constant to R.H.S and change its sign
Calculate
Change the sign on both sides of the equation
