Question

what is the slant height of this square pyramid?hint: dont forget to use your desmos calculator and staar reference sheet to help!(1 point)○ 14○ 8○ 289○ 17

Explanation:

Step1: Find half the base length

The base is a square with side 16, so half the side is $\frac{16}{2}=8$.

Step2: Use Pythagorean theorem

The slant height $l$ forms a right triangle with the pyramid height (15) and half the base side (8). Apply $l=\sqrt{15^2 + 8^2}$.
Calculate:

$$ l=\sqrt{225 + 64}=\sqrt{289}=17 $$

Answer:

17 (Option: ○ 17)
