Step-by-step explanation:
Given the area of the base of the oblique pentagonal pyramid is and the distance from the apex to the center of the pentagon is 6 cm. The measure of ∠ACB is 45°.
we know that
ABC is a right triangle
∠ACB=45°
AC=hypotenuse------> 6 cm
Now, volume of pyramid
Area of the base=50 cm²
so,
