Answer:
Obtuse triangle
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.
In right angle triangle, one angle is 90°. The square of the longest side (hypotenuse) is equal to the sum of the square of the two sides.
An acute triangle is a triangle with acute angles (less than 90°). The square of the longest side is less than the sum of the square of the two sides.
An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles (less than 90°). The square of the longest side is larger than the sum of the square of the two sides.
An isosceles triangle is a triangle with two equal sides.
Given a triangle whose side lengths are 8, 16, and 18, the longest side is 18.
Since no two sides are the same hence it is not an isosceles triangle.
Also, 18² > 16² + 8²; therefore this is an obtuse triangle
It took a while but the answer is Perimeter is 70ft
Step-by-step explanation:
As we have,
Subsitute the value and simplify
Answer:
Step-by-step explanation:
7√144 - 11√45 + 6√500
= 7(12) - 11√(9×5) + 6√(100×5)
= 84 - 11(3)√5 + 6(10)√5
= 84 - 33√5 + 60√5
= 84 + 27√5
678.24?
36 x 6 =216
216 x 3.14 = 678.24
I hope this helps! :)
