3^2 + 3^2 = c^2
9 + 9 = c^2
c = 3sqrt(2)
tan(x) = 3/3
tan(x) = 1
x = 45°
that means that the other one is 45°
ANS : 45°, 45°, and 90°

You know that there are 180° in a triangle. Since it is a right triangle, you then have 90° remaining for the last two angles. Since the lengths of the sides are equal, you know that the angles of the two sides also have to be equal. So, 90 = 2x , x = 45° for both angles

Are you sure the legs are each 3? If so it's isosceles and the other 2 angles are each 45 degrees.

because the sides are the same it is eqilateral therefore the angles are both 45 degrees all three always add to 180 degrees

as the other person said, since the sides r equal that means the angles are equal (45 degrees each).
To find the hypotenuse u can use pythag. theorem.

use the pythagorean theorem.
if one angle is 90...the other 2 are usually 45 and 45

cos(x/2) = sqrt(3) / 2 finding at a 30-60-ninety triangle, the cosine of 30 tiers, or pi/6 fits the invoice, yet be careful to incorporate the equivalent attitude interior the fourth quadrant for cosine x/2 = pi/6 OR x/2 = -pi/6 = 11pi/6 x = pi/3 or 11pi/3
