Repeat the procedure using angle C instead of angle B to find the measure of the side opposite angle C (side C). For the example: Multiply the sine of angle C (105) by the length of side A and divide the answer by the sine angle A (30): sine 105 = 0.97 x 10 = 9.7/0.5 = ...
Recall the Pythagorean Theorem. You can calculate the length of any side of a right triangle if you know the lengths of two sides using the pythagorean theorem. In addition, you can determine if a triangle has a right angle (90 degrees) if it satisfies the theorem, a^2 + b^2 = c^2...
(a) Calculate the length of each side of the right triangle and (b) Show that these lengths satisfy the Pythagorean Theorem. a) Find the lengths of the sides of the triangle with the given vertices (-1-,0,-2), (-1,5...
Perimeter of a triangle = Area of Equilateral Triangle:[ (Sqrt(3)/4)×(side)² ] Enter the length = Area of a equilateral triangle= Area of Triangle SAS(2sides & opposite angle):[ ½×a×b×SinC ] Enter the length and breadth = Angle = Area of a triangle SAS= Next...
To solve the problem of calculating the area of a triangle with sides of lengths 13 cm, 5 cm, and 12 cm, and then finding the altitude corresponding to the longest side, we can follow these steps:1. Identify the sides of the triangle
This means forming a right angle between the unknown object, the known object and your own position, and using the angle between the two objects to determine the length of the triangle's side that represents the distance to the unknown object. Historically, people would use sextants to measure...
Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together. For example, if the lengths of the sides measure 3 and 2, then squaring them would result in 9 and 4. Adding the squares together results in 13. ...

We can calculate the angle between two sides of a right triangle using the length of the sides and the sine, cosine or tangent. To do this, we need the inverse functions arcsine, arccosine and arctangent. If you only know the length of two sides, or one angle and one side, this is...
