X=80 because the square it cut in half so both triangles have the same measure in angles a square has to equal 180 the two measure Gaven are 80 and 20 which makes 100 .180-100=80
x=80
We're going through all the shapes.
A sphere has volume
A hemisphere has half the volume and a radius is half a diameter.
The answer is C, "ABCD are right angles", because rectangles only have 90 degree angles.
Answer:
x=2, y=5
Step-by-step explanation:
Answer: 135 Degrees
Step-by-step explanation:
There are 540 degrees in a pentagon, and we have three right angles. Three right angles measures 270 degrees, half of 540. So we have 270 degrees left, and we divide it by two since the angles are equal and get 135 degrees.
