Is there supposed to be a picture??
But to answer ur question when ur referring to x your referring to 1 hope this helps
The walls are vertical so the angle opposite X would be a right angle which is 90 degrees.
X would be 180 - 90 - 35 = 55 degrees
X and 2y - 5 are complementary angles which add together to equal 90:
2y - 5 + 55 = 90
Simplify:
2y +50 = 90
Subtract 50 from both sides:
2y = 40
Divide both sides by 2:
y = 20
Answer: 450 cm³ is the volume
Step-by-step explanation:
Volume of pyramid = L x W x H divide by 3
Not sure what you’re asking, but, if you’re looking for the expanded form... hope that helps?
I estimated it is around or near 360
