Work bout the height of this pyramid?

20 cm.

Step-by-step explanation:

In order to find the height, we need the volume and the base area first. We are already given the volume so we need to find the base area.

A = 18 · 5 = 90

Now that we know the base area is 90 cm², we can substitute the information into the equation to solve for the height.

V = 1/3(A)(h)

600 = 1/3(90)(h) (Given)

600 = 30h (Simplified)

20 = h (Divided 30 on both sides)

Therefore, the height is 20 cm.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
