x = 12

A = 144

Step-by-step explanation:

Angles A and B are the same so we can set them equal to each other

We can create the following equation

Reduce

4x = 48

x = 12

We the plug x into 10x + 24 in order to calculate angle A.

144

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:
