sin = -12/13 cos = 5/12 tan = -5/12 cosec = -13/12 sec = 12/5 cotan = -12/5
It is: cos^-1(12/13) = 22.61986495 degrees
It is about 67 degrees
No because otherwise it would be a right angle triangle.
5
5/13 = 0.3846 (to 4 dp)
sin = -12/13 cos = 5/12 tan = -5/12 cosec = -13/12 sec = 12/5 cotan = -12/5
It is: cos^-1(12/13) = 22.61986495 degrees
If you mean 5 by 12 by 13 then they will form a right angle triangle
The answer depends on which of the three angles 'a' is!
It is about 67 degrees
If the right angle is at A then SA = 5 mm.
Yes they do for a triangle using Pythagorean theorem 5 squared + 12 squared = 13 squared
Tan(f) = HG/FG = 12/5 = 2.4
By Pythagorean theorem, if the sum of squares of smaller sides of a triangle equals the square of longest side, it is a right angle triangle where the long side is the hypotenuse. 5 squared plus 12 squared is equal to 13 squared
If cos B is 5/13, find sin B, tan B, sec B, and cot B?sin= y/r= 12/13cos= x/r= 5/13tan= y/x= 12/5csc= r/y= 13/12sec= r/x= 13/5cot= x/y= 5/12x2+y2=r2
I think you have not asked the question correctly.I guess you meant that the sides of the triangle are 3, 4 and 5. Similarly you have given no indication of which angle is opposite which side.A 3, 4, 5 triangle is a right angle triangle (5 is the hypotenuse).Thus depending where angle B is, its sine will be:If B is opposite the side of length 3, sin B = 4/5If B is opposite the side of length 4, sin B = 3/5If B is opposite the side of length 5, sin B = 5/5 = 1; alternatively ∠B = 90° and sin B = sin 90° = 1
