In the summer, humidity interacts with the outdoor

In the summer, humidity interacts with the outdoor temperature, making a person feel hotter due to a reduced heat loss from the skin caused by higher humidity. The temperature-humidity index, Th, is what the temperature would have to be with no humidity in order to give the same heat effect. One index often used is given byTₕ= 1.98T 1.09(1-H)(T-58)-56.9, where T is the air temperature, in degrees Fahrenheit, and H is the relative humidity, expressed as a decimal. Find the temperature-humidity index if T = 82° and H= 55%. The temperature-humidity index at 82° and 55% humidity is □° (Round to one decimal place as needed.)
