Draw a triangle that has side lengths of 3cm and 6cm with an included angle of 120°. Determine if the given information makes a unique triangle, more than one triangle, or no triangle.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

236 cm 16 time 12 = 192

6 times 7 = 42

192+42
