Idk how to do this I need help

see explanation

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the3 given angles and equate to 180

x + 6 + 3x - 2 + 7x = 180, that is

11x + 4 = 180 ( subtract 4 from both sides )

11x = 176 ( divide both sides by 11 )

x = 16

Thus

∠ V = x + 6 = 16 + 6 = 22°

∠ W = 3x - 2 = 3(16) - 2 = 48 - 2 = 46°

∠ X = 7x = 7(16) = 112°

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:
