Answer:
its a hope this helps
Step-by-step explanation:
It will be roughly 67.08 inches.
We can solve this using the Pythagorean Theorem, which is listed below.

In this equation, we use a and b as legs of a triangle and c is the hypotenuse. We can treat the length and height of the bookcase as legs and use this equation to solve for the diagonal (also known as the hypotenuse)



67.08 = c

Answer:
x = 26.2 cm
Step-by-step explanation:
To find the value of x, we will use cosine rule;
x² = 15² + 18² - 2(15 × 18)cos105
x² = 225 + 324 - 540(-0.2558)
x² = 549 + 138.132
x² = 687.132
x ≈ 26.2 cm
