Square prism
because of the two squares on the side and it’s a prism not a pyramid because it just isn’t lol
All sides of an equilateral triangle are equal, so all three sides are 9 cm.
To find h, use the pythagorean theorem. This requires use of only one right triangle, where we use b as our h.
a^2+b^2=c^2
(4.5)^2+b^2=(9)^2
(20.25)+b^2=(81)
b^2=(81/20.25) or 4
square root both sides
b=2
Answer:
B
Step-by-step explanation:
The graph hits the x axis at 5, -2, and -3/
Answer:
11.4
Step-by-step explanation:
You have to use the Pythagorean theorem: c = √(a² + b²)
√(7² + 9²) ≈ 11.4
