Questions: 1. what is the value of x? show your work to justify your answer. 2. what is the value of the exterior angle? show your work to justify your answer.

x = 72

Exterior angle = 154

Step-by-step explanation:

82 + x = 2x + 10

Subtract x from both sides

82 = x + 10

Subtract 10 from both sides

72 = x

Exterior Angle

2(72) + 10

154

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:

it is only things thain can be deafeated
