The largest angle will be opposite the biggest side which is 14 cm and so by using the cosine rule its angle works out as 106.23 degrees rounded to two decimal places.

What is the largest angle of a triangle with sides of 14 cm 8.5 cm and 9 cm?
The largest angle of the triangle will be opposite its largest side and by using the Cosine Rule it works out as 106.23 degrees.
What is the largest angle in and area of a triangle with sides of 14 cm by 9 cm by 8.5 cm?
Using the cosine rule the angle can be found:Largest angle is opposite largest side→ A = arc cos ((14² - 9² - 8.5²)/(2 × 9 × 8.5)) ≈ 73.8°For the area, use Heron's formulaLet S = half the perimeter = ½(14 + 9 + 8.5) = 15.75Area = √(s(s - a)(s - b)(s - c))= √(15.75 × (15.75 - 14) × (15.75 - 9) × (15.75 - 8.5))≈ 36.73 sq cm.Alternatively, you can use the Sine ratio on the largest angle and the two shorter sides:area ≈ ½ × 9 × 8.5 × sin 73.8 ≈ 36.73 sq cmAnother Answer: The largest angle of the triangle is 106.23 degrees and its area is 36.73 square cm both rounded to two decimal places
What is the largest angle and area of a triangle with sides of 14 cm 9 cm and 8.5 cm?
The largest angle will be opposite the longest side which is 14 cm and by using the cosine rule it works out as 106.23 degrees rounded to two decimal places and its area is 0.5*9*8.5*sin(106.23) = 36.726 square cm to three decimal places.
What is the triangle with three 14 - cm sides?
It is an equilateral triangle that has 3 equal sides of 14 cm
If an isosceles triangle has two equal sides that are 14 feet long and the third side is 17 feet long what are the angles?
Let the Isosceles Triangle be ∆ ABC with sides AB = AC = 14', and BC = 17' Draw a line bIsecting angle BAC. This line will be perpendicular to and bisect BC at point D. Then ∆ DBA (or ∆ DCA) is a right angled triangle with AB the hypotenuse. Angle ABD = Angle ABC is one of the two equal angles of the isosceles triangle. Cos ABD = BD/AB = 8.5/14 = 0.607143, therefore Angle ABC = 52.62° The third angle of the triangle is 180 - (2 x 52.62) = 180 - 105.24 = 74.76° The angles are therefore 52.62° , 52.62° and 74.76° .

Can sides 19 13 14 make a triangle?
Yes they could. The only requirement is that if you add any two sides together they are longer than the third. 19 + 13 > 14; 19 + 14 > 13, and 13 + 14 > 19, so those sides can make a triangle.
