1 cm is the base of the triangle
Based on the starting temperature and the new temperature, the relevant expression would be<u> 2 - (-9) </u>
To find the number of degrees the temperature has changed by, use the following equation:
<em>= Starting temperature - Current temperature </em>
Starting temperature = 2°F
Current temperature = -9°F
The equation becomes:
<em>= 2 - (-9)</em>
In conclusion, the expression would be 2 - (-9)

x = 30
Step-by-step explanation:
A triangle's angles add up to 180
Also, angles on a straight line add up to 180
180-100 = 80
80+70=150
180-150=30
180 votes is the correct answer
