A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.
The sum of the areas of the two squares on the legs of a triangle (a and b), where the angle between sides a and b is 90 degrees, equals the area of the square on the hypotenuse (c). a2 + b2 = c2
when you multiply the area of the small triangle by four it equals the area of the large triangle.
The right-angle triangle measures 28cm by 35cm. Such a triangle is half of a rectangle.Therefore 28 x 35 = 980cm2 is the area of a rectangle.980 / 2 = 490cm2 will give the area of the triangle (which is 490cm2).
The basic formula is: A = 1/2bh where A is area, b is the base of the triangle and h is the height Using trigonometry, the area of a triangle can also be expressed as: A = 1/2absinC, where A is the area, a and b are two sides of the triangle, and C is the angle between those sides.
1 Angles are measured in degrees, minutes and seconds 2 Angles greater than 0 but less than 90 degrees are acute 3 Angles of 90 degrees are right angles 4 Angles greater the 90 but less than 180 degrees are obtuse 5 Angles greater than 180 but less than 360 degrees are reflex 6 Angle of 360 degrees is a full rotation 7 Triangles are 3 sided polygons 8 Triangles have 3 inside angles that add up to 180 degrees 9 Triangles have 3 outside angles that add up to 360 degrees 10 Triangle that is scalene has 3 different acute angles 11 Triangle that is a right angle triangle has a 90 degree angle and 2 acute angles 12 Triangle that is obtuse has 1 obtuse angle and 2 acute angles 13 Triangle that is isosceles has 2 equal base angles and 2 equal sides 14 Triangle that is equilateral has 3 equal inside angles and 3 equal sides 15 Triangles have no diagonals 16 Triangles will tessellate leaving no gaps or overlaps 17 Triangle's area is 0.5*base*perpendicular height 18 Triangle's perimeter is the sum of its 3 sides 19 Triangle as a right angle triangle is subject to Pythagoras' theorem 20 Triangles are subject to the rules of trigonometry 21 Triangles are the corner stones of all other polygons
It is 12.2 degrees.
Angle C must equal 79 degrees because there are 180 degrees in a triangle. Use the sine rule to find side b: 15/sin79 = b/sin63 b = 15*sin63/sin79 = 13.61524832 units Use 1/2*c*b*sin38 to find the area: 1/2*15*13.61524832*sin38 = 62.86787901 square units
To an appropriate degree of accuracy and using the sine formulae the other lengths are 3.81 cm and 4.20 cm with the area of the triangle being 7.81 square cm.
This is not a triangle. All three angles of any triangle must always add up to 180o. The angles you gave add up to only 59.9o.
Yes, that works for any triangle. The height always has to be at a right angle to the base. If there is an angle over 90 degrees, you may have to extend the base.Yes, that works for any triangle.

Using cosine rule largest angle is 106.23 degrees to two decimal places. Area of triangle: 0.5*8.5*9*sin(106.23) = 36.73 square cm to two decimal places.
The sum of the areas of the two squares on the legs of a triangle (a and b), where the angle between sides a and b is 90 degrees, equals the area of the square on the hypotenuse (c). a2 + b2 = c2
The area of triangle is : 21.0
the area referrers to the length and circumference of the triangle it self. The measurement matters to find the acute angle it self as a angle not a triangle
Using cosine rule largest angle is: 106.23 degrees Using area formula: 0.5*9*8.5*sin(106.23) = 36.726 square mm
Using trigonometry the angles are 90 degrees, 59.5 degrees and 30.5 degrees with an area of 133.8896 square cm.
If it's a right angle triangle then the dimensions of one of its sides is also needed
