What are all the other two angles in a right angle triangle?

The small (very small) angle is arcsin(1/1000).

This is 0.001 radian approx. or 0.0573 degrees

The other angle is 89.9426 degrees.

Hypotenuse = 100mm

Side opposite to it (perpendicular) = 0.1mm

Therefore,

sin ('theta') = 0.1/100 = 0.0001

Therefore,

'theta' = sin(^ -1) 0.0001= 0.005 degree

So, the other angle is = 180-90-0.005= 89.995 degree.

['Theta' is the angle opposite to the right angle]

Thus,

The angles are 90,89.995,0.005.

(Are you sure it is a triangle? It does not seem like one. The angles are too odd you know! Also hope that you know inverse circular functions 'cause there is no other way to do the sum.)

I refuse to answer your question due to the fact that a triangle has no apposite (sic) sides. There are only three. Learn basic mathematical terms.

one angle = inverse cosine 1/1000

other angle = inverse sine 1/1000

the other two angles are acute angles ie they have measure between 0-90 degree.....

SOH-CAH-TOA. That's all you need.

formula is : a^+b^=c^
