If the sides are 10cm, 17cm and 21cm, the three angles are approx 28, 53 and 99 degrees. It is an obtuse angled triangle.
yes
To find the area of a triangle, you use the formula: Area = 1/2 * base * height. Plugging in the values, we get Area = 1/2 * 10cm * 15cm = 75 square cm. Therefore, the area of the triangle with a base of 10cm and a height of 15cm is 75 square cm.
You could measure a skateboard in decimeters. Remember, 1dm=10cm.
For certain angles, the answer is yes. For 30o to the horizontal (in the positive x direction), you need to measure the horizontal distance to be twice the vertical distance. For example, draw a triangle with a base length of 10cm and, at a right angle to the base, measure a height of 5cm. The angle to the horizontal (the smaller angle) will be 30o. (The opposite is true for the angle of 60o).
The area of triangle is : 60.0
No because an isosceles triangle has 2 equal sides and 2 equal interior angles with another angle and the 3 angles add up to 180 degrees
if it is a scalene triangle yes scalene triangle have no congruent sides and angles
Size or internal angles?
It is a right angle triangle and its largest angle is 90 degrees
Using the cosine rule gives the largest angle of the triangle as 91.04179885 degrees or 91.042 degrees rounded to 3 decimal places. So: 91.042-90 = 1.042 degrees
a triangle?
yes
There are 5 linear measures given. If that implies that the shape is a pentagon, there is no way to answer the question with out additional information about the angles in the pentagon. A triangle is the only polygonal shape whose area is uniquely determined by the length of its sides.
It is impossible to find the height of a triangle with just it's base.
It can't.
