Zero triangles.. we cant draw triangle with these angles. but the given angles are 45,64.72. if we add those we get 45+64+72=181. so we cannot draw triangle.

The sum of all three angles in any triangle anouamo to 180°. If we add the given angles, i.e., 45°+64°+72°,gives us 181°. So, no triangle exists with the given angles.

no traingle can be drawn with this measurements because the total sum of traingle =180 so its exceeds the angle

Only one distinct triangle can be formed.We can make infinite numbers of triangle by scaling up or down its length.

Zero triangles. because we cant draw triangle with these angles. As the given angles are 45,64,72. if we add then we get, 45+64+72=181.so we can't draw triangle.

Zero triangle.For a triangle the sum of its three angle=180 degrees..But if we add 45+64+72 we get 181...so we can't construct a triangle

What is the value of Sin360+Cos360?
Sin(360)= sin(0)=0 Cos(360)=cos(0)=1 Formula: Sin((360*x)+y)=sin(y) Cos((360*x)+y)=cos(y) Where x is any integer and y is any real number. Sin(360) +cos (360) =1
