How do you find the other side of a right triangle?
use right triangle trig... sin (angle) = opposite side/hypotunese, cos (angle) = adjacent side/hypotunese, and tan (angle) = opposite side/ adjacent side
What is the hypotenuse of a right triangle with the adjacent side measuring 4.0 and a degree of 58?
Cos(58) = 4/Hypotenuse so H = 4/Cos(58) = 7.55 units.
How do you find the base of a triangle if is not given?
You use trigonometry. If the triangle is a right triangle, then you can use the Pythagorean theorem (a2 + b2 = c2 where c is the hypotenuse). This requires you to know two of the sides of the triangle. You can also use the relationship: sin A = a/c cos A = b/c tan A = a/b where "A" is a non-right angle of a right triangle, "a" is the length of the side opposite of the angle "A", "b" is the length of the side adjacent to the angle "A" and "c" is the length of the hypotenuse. If the triangle is NOT a right triangle, you can use the law of sines or the law of cosines. The law of sines: a /sin A = b / sin B = c / sin C where "a" is the side opposite of angle "A", "b" is the side opposite of angle "B" and "c" is the side opposite of angle "C". The law of cosines: a2 = b2 + c2 - b*c*cos A b2 = a2 + c2 - a*c*cos B c2 = a2 + b2 - a*b*cos C where "c" is the hypotenuse, "a" and "b" are the other sides of the triangle and "C" is the angle opposite of "c", "B" is the angle opposite of "b" and "A" is the angle opposite of "a".
How do you work out the hypoteneuse side of an isosceles triangle if the triangle is not right-angled and two of the sides and the angle between them are known?
Use the cosine rule: a2 = b2+c2 - 2bc*cos A An isosceles triangle has two equal sides.
What is cos in a math problem?
Its a ratio in a right angle triangle, cos angle = adjacent / hypotonuse.
How do you find the cos of a triangle?
Adjacent side / Hypotenuse
What Is the value of cos?
Cos is the ratio between adjacent side (of the given angle thieta) to the hypotenuse of the triangle.
How do you find the other side of a right triangle?

What is the hypotenuse of a right triangle with the adjacent side measuring 4.0 and a degree of 58?

What is the length of side C of a triangle when side A and side B and angle AB are known?
C = sqrt(C2) C2 = A2 + B2 - 2 A B cos(AB)
How would you find out the sin tan and cos of right angle triangle?
sin, tan and cos can be defined as functions of an angle. But they are not functions of a triangle - whether it is a right angled triangle or not.

Its a ratio in a right angle triangle, cos angle = adjacent / hypotonuse.
What is cos X?
At the most basic level, cos(x) represents the cosine of an angle x, a trigonometric function. In a right angled triangle, where one of the angles is x, cos(x) is the ratio of the lengths of the short side next to the angle x (the adjacent side) and the hypotenuse (the side opposite the right angle). Soon afterwards, you learn that this measure is a characteristic of the angle x, not of the triangle, so you do not actually need a triangle! Any angle x has a cos(x) associated with it, whether it is in a triangle, in another shape or simply a free-standing angle. Later still, you learn that sin(x) is an infinite series of the form: cos(x) = 1 - x2/2! + x4/4! - x6/6! + ... where x is the angle measured in radians, and n! [n factorial] is n*(n-1)*(n-2)*...*3*2*1 Alternate answer: X is a variable representing the measure of an angle. Cosine, abbreviated cos, is a ratio of two sides of a right triangle containing the angle X. but not any 2 sides, 2 specific sides of the triangle. (ratio means a fraction, which is usually divided to give a decimal answer) One of those sides is called the adjacent and the other is called the hypotenuse. The third side is called the opposite. Cos X = Adjacent side / hypotenuse
What is socahtoa?
SOH CAH TOA is a way of remembering what the functions sin, cos, & tan mean in a right angle triangle. With a triangle with one of the acute angles labelled (theta) the longest side H (Hypotenuse), the side opposite the labelled angle O, and the short side closest to the angle A (Adjacent) SOH ->SIN(Theta)=0/H CAH ->COS(Theta)=A/H TOA ->TAN(Theta)=O/A
How do you find perimeter of triangle when two sides are not given?
You have to figure out the two sides. You must have the angles of the triangle and use the sin, cos, and tan functions to figure out the sides. Remember "Oscar Had a Hint of Apples?' sin (x) = o/h cos (x) = a/h tan (x) = o/a So, if the hypotenuse is the only side known, multiply the sin of the angle of the opposite side by the hypotenuse. This gives you the opposite side. Then you can divide the tangent of the angle by the opposite side to get the adjacent side.
