What is x need help asap???
Alik [6]
You will notice that 48°, x, and x lie upon a straight line.  The sum of those angles must then be equal to 180°.  Which means:

48+x+x=180

48+2x=180

2x=132

x=66°

Nadya [2.5K]

Answer: \Large\boxed{20 < h < 80}

Step-by-step explanation:

<u>Given inequality </u>

|h-50| < 30

<u>The goal of the question</u>

To find the minimum and maximum of the relative humidities

For this question, we need to solve the inequality

<u>Simplify the absolute value sign</u>

h-50 < 30          or          h-50 > -30

<u>Add 50 on both sides</u>

h-50+50 < 30+50          or          h-50+50 > -30+50

       \Large\boxed{h < 80}                   or                    \Large\boxed{h > 20}

Hope this helps!! :)
