Question

tribhuj abc ak samkon tribhuj hai jisme angle c 90 dhigri hai cos( A+B ) ka man​

Answer 1

Answer:

tringle abc

त्रिभुज के तीनों कोणों का योग 180 डिग्री होता है

इस तेलुगुज में हमें एक कौण 90 डिग्री दिया हुआ है

अतःangleA+angle B+ angleC=180

angle A+angle B+90=180

angle A+Angle B=180-90

A+B=90

अतः, cos(A+B)=cos(90)=0

Answer 2

The required answer is 0.

right angle triangle: A right triangle is a type of triangle that has one of its angles equal to 90 degrees. The other two angles add up to 90 degrees. The sides that include the right angle are perpendicular and the base of the triangle. The third side is called the hypotenuse, which is the longest side of the three sides.

The three sides of a right triangle are related. This relationship is explained by the Pythagorean theorem. According to this theorem in a right triangle

Hypotenuse2 = Perpendicular2 + Base2.

The area of ​​the largest square is equal to the sum of the squares of the two other small squares. We can generate the Pythagorean theorem because the square of the length of the hypotenuse is equal to the sum of the length of the squares of the base and the height.

The given is ΔABC is right angle triangle,where ∠C=90⁰

We need to find the value of cos (A+B).

We know that sum of all angle of a triangle is 180⁰.

Therefore

∠A +∠B +∠C = 180⁰,

I.e.   ∠A +∠B =180⁰ -∠C

         ∠A +∠B =180⁰ - 90⁰ [ The given is ∠C=90⁰]

          ∠A +∠B =90⁰

Now cos(A+B) =cos 90⁰= 0

Hence the required answer is 0.
