Use the Pythagoras Theorem in the corresponding right angled triangles.
Answer:
z = 110
Step-by-step explanation:
z + 35 + 35 = 180
z+70=180
z = 110
10xBx15+11xB is that what you are needing for the answer because you didn't really say what you where looking for.
6.) 9
5(9)+18=63
Divide 9+13x (since its the entire line) by 2 to get 4.5+6.5x so it can equal Half
4.5+6.6(9)=63
7.) IF=HF
The three lines indicate they are equal to eachother
Hope that helps!
