Answer:
No, it is not a right triangle.
Step-by-step explanation:
Given:
The sides of the triangle = 15 10 and 7
To Find:
Whether the triangle is a right triangle = ?
Solution:
According to Pythagorean theorem , In an right triangle the the sum of the squares of the two smaller sides must equal to the square of the larger side

where
a and b are the smaller sides
c is the larger side
Now from the given data, lets assume
a = 10 and b =7 and c =15
Substituting in the above equation we get,

100 + 49 = 225
149 = 225

So, the given triangle is not a right triangle.

Answer:
127.17cm²
Step-by-step explanation:
Area of a semicircle: πr² ÷ 2
d = 18
r = 18/2 = 9
Area of a semicircle: 9²π ÷ 2 = 127.17cm²
