A combination square
It should be approximately 1.26 inches, or 1 1/4 inch to the nearest quarter inch. The tangent of an angle of 1 degree is 0.17455 times the 6 foot base is 0.10473 feet.
If those are the lengths of the triangle's sides, then you have a "right" triangle. The angle opposite the 5-inch side is a 90-degree angle.
The take-out for a 4-inch long radius degree weld elbow (or ell) is typically determined by the radius of the elbow and the pipe diameter. For a long radius elbow, the centerline radius is usually 1.5 times the pipe diameter; therefore, for a 4-inch diameter pipe, the centerline radius would be 6 inches. The take-out length is generally the distance from the end of the pipe to the point where the elbow connects, which can be calculated based on the elbow's radius and the angle of the bend. For a 90-degree elbow, the take-out would be approximately equal to the radius plus the straight length of the pipe before and after the elbow, typically resulting in about 9 to 10 inches.
The hypotenuse of a 90-degree triangle with two nine inch sides is: 12.73 inches.

1/2 inch
A degree is a measure of temperature or angle. An inch is a measure of length. Without further information an answer to this question cannot be given.
6 inch or 4 inch if it's a short radius
If those are the lengths of the triangle's sides, then you have a "right" triangle. The angle opposite the 5-inch side is a 90-degree angle.
4 1/2 inch
39in.
It equals 3/4" in length.
It depends upon where the leg is. Assuming the 49 inch leg is opposite of the 36 degree angle, we know the third angle is 54 degrees (sum of a triangle's angles is 180 degrees). The law of sines states that the ratio of the sine of an angle to the side opposite the angle is equal for all three angles. This means that sin(36)/49 = sin(54)/x where x is the length of the side opposite the 54 degree angle. Solving that equation gets x = 67.44. Using the Pythagorean theorem, 49^2 + 67.44^2 = c^2 where c is the length of the hypotenuse. Solving yields c = 83.36. Summing the three sides together yields 49 + 67.44 + 83.36 = 199.80 inches. If the 49 inch leg is adjacent to the 36 degree angle, swap 49 and x for the law of sines equation and solve.
