Question

Find x, the slant height of the pyramid shown, to the nearest tenth.

Answer 1

I just did this question and 5 mm is not the answer the actual answer is (D. 4.3 mm) Because when I looked back it said 5 mm isn't the answer so this is what I'm gonna leave here. that dude below has the wrong answer.

Answer 2

There is a right triangle with the height (4) and half the base (3) as legs and the slant height (x) is the hypotenuse:
4² + 3²= x²
x² = 16+9
x =5 mm
