Answer:
y = 25 degrees
Step-by-step explanation:
straight line has 180 degrees
so 180 - 115 = x which is 65 degrees
traingle has 180 also
65 + 90 = 155 180 - 155 = y which is 25 degrees
The triangle on the other side is the equivalent.

Answer:
700.4 cm
Step-by-step explanation:
Use a proportion.
Let x be the vertical distance for the 700 cm pipe.
1 cm is to 30 cm as x cm is to 700 cm
1/30 = x/700
30x = 1 * 700
30x = 700
3x = 70
x = 70/3
Now we need l. We have a right triangle with legs measuring 70/3 cm and 700 cm, and we are looking for the hypotenuse l.
a^2 + b^2 = c^2
(70/3)^2 + 700^2 = c^2
c^2 = 4900/9 + 490000
c = 700.4
l = 700.4 cm
