This is geometry so me, you. this is about special angle pairs. what is m angle 7=3x+80

m angle 7 is 134 degrees

Since 3x+80+9x-116=180 since 7 and 8 are supplementary. This helps you find x which equals 18. After plug in x=18 into 3x+80 and you will get angle 7 is 134.

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

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.
