A triangle is a special right triangle (a right triangle being any triangle that contains a 90 degree angle) that always has degree angles of 30 degrees, 60 degrees, and 90 degrees Because it is a special triangle, it also has side length values which are always in a consistent relationship with one anotherNow that the diagram is complete, you should have a triangle with all three sides labelled Use this triangle to fill in the table below with EXACT VALUES for each trigonometric function DO NOT use your calculator here 15° 75° sin θ cos θ tan θ csc θ sec θ cot θ 6 Use your calculator to check each value in your table Do the values you foundAn isosceles triangle with angles 150, 15, 15 Source Florida Center for Instructional Technology Clipart ETC (Tampa, FL University of South Florida, 09)

What are the angles and sides of this 15°75°90° triangle?Right Triangle Calculator Although all right triangles have special features – trigonometric functions and the Pythagorean theorem The most frequently studied right triangles , the special right triangles, are the 30, 60, 90 Triangles followed by the 45, 45, 90 trianglesLet A,B,C denote the sides of a triangle, and let a,b,c be the angles across from that side Then law of sines shows that they must have the ratio sin (a)/A = sin (b)/B = sin (c)/C So let C be the hypotenuse, let a = 15° and let b=75° Then, A = C * sin (15°) and B = C * sin (75
Scalene triangle with 90, 75, abd 15 degree angles Shortest side is 5 inches What are the other two side lengths?It's a right triangle, so that makes it easier The short side is opposite the small angle, 15 , so 5 = hyp*sin (15) hyp = 5/sin (15) =
