Start by adding together the shortest two sides, 7 and 8.7 inches. Result: 15.7 inches. Because this sum is greater than the longest side, 15.4 inches, it's possible to construct a triangle, whose largest angle will be close to 180 degrees.

The surface area of the square pyramid if the length of the sides of the base are 10 cm, and the slant height is 15 cm is 416.2 cm²
<h3>Surface area</h3>
Surface area of the square pyramid
= a² + 2a√a²/4 + h²
where,
- a = sides of base = 10 cm
- h = slant height = 15 cm
Surface area of the square pyramid
= a² + 2a√a²/4 + h²
= 10² + 2(10)√10²/4 + 15²
= 100 + 20√100/4 + 225
= 100 + 20√25 + 225
= 100 + 20√250
= 100 + 20(15.81)
= 100 + 316.2
= 416.2 cm²

Answer:
Subtract (remove) 2 x-tiles from both sides.
x = 5
Step-by-step explanation:
According to the rules of equality, you can add or subtract the same number(s) from both sides of the equal sign. Here, it is convenient to subtract the number of tiles that is on the side with the least number of tiles. That means we want to subtract 2 x-tiles from both sides.
The result of doing that is the answer:
x = 5
