Answer:
849.24 cm²
Step-by-step explanation:
we know it is a cube so to find the surface area of each square you do
12x12=144 and there are 5 sides so 144x5=720
We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle
Now using pythagorus you would do a²+b²=c²
15²+6²=c²
225+36=c²
√261=√c²
16.15=c this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24
now add 720+129.24=849.24 cm²
Answer:
90 degrees
Step-by-step explanation:
Sum of the angles in a triangle = 180°
Opposite angles are equal
For two parallel lines and a transversal,
corresponding angles are equal, and
alternate angles are equal.
45+45=90.
180-90=90
Plus, you can see that the angle forms a perfect 90 degree angle.
All it’s asking is how many students basically scored 90 and under. there’s a total of 25 kids and 14 scored a 90 or less.
