Angles may be measured in three angles:degree, radian and gradians (grads).

tan(45 deg)=1

tan(45 radians)=1.61977

If your problems require angles to be measured in degrees, make sure that the calculator's angle unit is set to degrees.

In RUN screen press [SHIFT][MENU] (SetUp) select the angle line and press function key under the tab Deg (should be F1).

I presume that x is the measure in degrees of the third angle. Use the fact the sum of the interior angle of a triangle is equal to 180 degrees.

x+128+37=180

x+165=180

x=180-165=15 degrees.

x+128+37=180

x+165=180

x=180-165=15 degrees.

Let i be the measure of the angle of incidence; let r be the measure of the angle of refraction. Both angles are measured from the normal to the surface at the incidence point. Let n_i be the index of the first medium where the incident ray lies. Let n_r be the index of refraction of the second medium.

The law of refraction states that** n_i*sin(i)=n_r*sin(r)**

Assuming that the first transparent medium is air, we have n_i=1. Solving for n_r we find

**n_r=(n_i*sin(i))/sin(r)**

For i_r=32 degrees, and r=15 degrees

n_r=sin(32)/sin(15)=2.0475

Here is some help

180deg is equivalent to Pi radians

Take some angle. Its measure in degrees is say x_deg, Its measure expressed in radians is x_rad.

The fraction of 180 deg that the angle represents is equal to the fraction of PI that this angle represents.

Conclusion: the ratio x_deg/ 180 deg must be equal to the ratio of x_rad/PI

x_deg/180 deg=x_rad/PI

Isolate X-rad in the above equation. Some will tell you to cross multiply.

x_rad=(Pi/180)*x_deg

Application: x_deg=-525 in radians?

x_rad= (PI/180)*(-525)=-(525/180)*PI

Keep the value (525/180) as a fraction reduced to its simplest form. The result is 35/12

You did not mention the brand or model of your gun, however, you can determine the angle needed by placing a straight edge in line with the path of the driver and measure the angle from this edge to rails.. If the straight edge to the rails measure 90 degrees or makes a right angle, you need "0 degree" nails, if it measures 80 degrees, you need "15 degree" etc. Most generic nials 15 gauge nails will work. No need to by branded nails unless your gun requires an unusual angle. Good luck.

Place you protractor over the angle to be measured. Make certain the centre line is aligned with the apes (point) of the angle and one arm (of the angle) is aligned with the protractor's bottom edge. You can now read off the size of the angle by noting the position of the other arm under the protractor's degree scale.

nine times the degree measure of the one of two complementary angles equals six times the degree measure of the other. find the measure of the angle.

A **linear pair of angles** is formed when two lines intersect. Two angles are said to be **linear** if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

A pair of angles is said to be**vertical** if the angles share the same vertex and are bounded by the same pair of lines but are opposite to each other. Such angles are congruent and thus have equal measure

A pair of angles is said to be
