In ΔHIJ, the measure of ∠J=90°, the measure of ∠H=23°, and JH = 2 feet. Find the length of HI to the nearest tenth of a foot.

2.2 feet

Step-by-step explanation:

If your here from delta math that’s the answer

31.5

Step-by-step explanation:

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:
