The Law of Sines: a/sin A = b/sin B = c/sin C
24/sin 42˚ = c/sin (180˚ - 42˚ - 87˚) since there are 180˚ in a triangle.
24/sin 42˚ = c/sin 51˚
c = 24(sin 51˚)/sin 42˚ ≈ 28

What is the measure of angle A in triangle ABC if B equals 15 degrees C equals 65 degrees and side a equals 19?
If you are really talking about a closed triangle ABC, then the length of side "a" (given as 19) does not matter in the calculation. Sum of the angles of a triangle is 180 degrees. Angle B and C add up to 15 + 65 = 80 degrees. Hence angle A is (180 - 80) = 100 degrees
A kite string makes an angle of 41point3 degrees with the level ground when the kite is 114 ft high how long is the string?
In effect, you have a right-angled triangle with an adjacent angle of 41.3o and an opposite side of 114 feet. There are several ways to find the length of the string (which in effect is the hypotenuse of the triangle), but in this case, the quickest way is to use the sine ratio. For any right-angled triangle: sin angle = opposite/hypotenuse. Rearranging the equation: hypotenuse = opposite/sin angle hypotenuse = 114/sin 41.3o hypotenuse = 172.7268362 feet. Therefore, the string is 173 feet in length correct to the nearest foot.
Different kinds of triangles in terms of sides?
An isosceles triangle has two sides the same length. An equilateral has all 3 sides the same length. A scalene triangle doesn't have any sides that are the same length.
What statement is true about 45-45-90 triangle?
It is a right angled triangle with legs of equal length.
How do you find the length of one side of a triangle?
The answer depends on what information you do have.

What is the length of the hypotenuse of the right triangle if AC equals 6 and AD equals 5?
The length of the hypotenuse of a right triangle if AC equals 6 and AD equals 5 is: 7.81
How do you know when a triangle is 90 degrees?
we know that a triangle is 90 degrees by measuring its length or it can be known as right triangle which measures 90 degrees.
Given triangle ABC angle B is 38 degrees angle c is 56 degrees and BC equals 63 cm find the length of AB?
52.4 cm
What is a triangle with all three sides equals in length?
It's called an 'equilateral triangle'.
What are the 30-60-90 triangles?
In a right triangle where two other angles are 30 and 60 degrees, the side opposite to the 30 degree angle has a length that equals the half of the hypotenuse length.
Area of an isosceles right angled triangle?
The area of a right angled triangle would be .5 * length *width where the length is the height of the triangle. To find the height of the triangle, take the sine of 45 degrees, which is the degree of the angles other than the 90 degrees, and multiply it by the length of one of the two equal sides. The width of the triangle is the length of the bottom side.
Can the sum of two sides of a triangle be less than the third side?
Yes. Lets say one side is 110 degrees. A triangle equals 180 degrees so the rest is split into 70 degrees. So one side is 110 and the 2 others are 70 degrees which would be yes. No. The sum of the lengths of any two sides of a triangle will always be more than the length of the third side of the triangle.
Which is a triangle with no sides the same length and an interior angle measuring 90 degrees?
This is a right triangle.
What is the length of rt if rs equals 6 and st equals 6 and mo equals 11 and triangle rst equals triangle mno?
If triangle RST equals triangle MNO then RT = MO = 11 units. All the rest of the question - the lengths of RS and ST are irrelevant.
