<h3>What is a triangle?</h3>
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.
The length of different sides are:
Since the length of all the sides of the triangle is not equal it is a scalene triangle.
Hence, the correct option is A.

Remove the parentheses around the expression 1
115 = 10X + 0.25(60)
115 = 10x +15 (this is the equation to use)
100=10x
x=10 hours
Since it is a right angle you would subtract 57 from 90 because both angles added together are 90°. 90-57= 33°
