The 'included' angle between sides 9 and 8.5 is 106.225 and so the area of the triangle is 0.5*9*8.5*sine(106.225) = 36.727 square cm rounded up to 3 decimal places.
Yes - by the Pythagorean Theorem, if it is a right triangle, the square of the hypotenuse will be equal to the sum of the squares of the other two sides. 36² =1296 77² = 5929 85² = 7225 since 1296 + 5929 = 7225 i.e. 36² + 77² = 85² a triangle with sides 36, 77, and 85 will be a right triangle with the hypotenuse being the side of length 85 and the right angle being the angle between the sides of length 36 and 77.
Just add the 3 sides: 5+6+7 = 18m
A triangle with no congruent sides is called a scalene triangle. If it has a 95-degree angle, the other two angles must be less than 85 degrees each since the sum of all angles in a triangle is 180 degrees. The lengths of the sides will vary, with the longest side opposite the largest angle, which in this case is 95 degrees. Therefore, the triangle will have all sides of different lengths corresponding to its angle measurements.

The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
First: Sides are not acute or obtuse. ANGLES are acute or obtuse. An acute triangle has to have all angles acute. Examples: 60, 60, 60 70, 60, 50 45, 50, 85 45, 45. 90 30, 60, 90 But if one of the angles is obtuse (>90 degrees), then the other two must be acute. Of course, *this* triangle would not be called an acute triangle, because one of its angles is abtuse; it would be called an obtuse triangle.
85 ÷ 14 = 6 with remainder 1
An acute angled scalene triangle.
All the angles are smaller than 90o, so triangle is acute triangle.
