The measures of the three angles of a
triangle are given by 3x + 1, 2x - 3. and 9x.
What is the measure of the smallest angle?
A 13° C 290
B 23° D 40°

B 23°

Step-by-step explanation:

(3x + 1) + (2x - 3) + 9x = 180

14x = 182

x = 13

smallest angle: 2 x 13 - 3 = 23

y=mx+b is the final answer!   : )

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
