Answer:
11.7
Step-by-step explanation:
pythagorean theorem is 
apply that same formula soo 
then sqaure root 136
round that soo now the answer is 11.7
So WX is 7y +4 and XY is 21, and when you add those lines you get the whole thing, which is 12y so write that like an equation
12y = 7y+4+21
12y = 7y+25
5y = 25
y = 5
Answer:
1200
Step-by-step explanation:
the information on it
X=70, y=55
The triangle is an isosceles triangles. In an isosceles triangle, the base angles are congruent.
Then use the triangle angle sum theorem and set the equation to 180.
55+55+x=180
110+x=180
x=70
The angle with 55 degrees and the angle with the variable y are alternate angles. Meaning they are congruent.
