Answer:
m∠6 = 116°
Step-by-step explanation:
<u>first find x:</u>
7x - 17 = 2x + 78
subtract 2x from both sides: 5x - 17 = 78
add 17 to both sides: 5x = 95
divide by 5: x = 19
<u>plug x into 7x - 17</u>
7(19) - 17 = 116
∠6 and 7x - 17 are vertical angles and therefore congruent, so m∠6 also = 116°
First you should set up fractions equal to each other to see the size ratio
8/34 = x/1.2
As to make comparable fractions. Then you would cross multiply in order to get

Divide both sides by 34 and you should get an answer of 0.28m for the model beam.
If the question is, "What is the scale factor." That would be a scale (factor) of 2.
Answer: -1
Step-by-step explanation: So if the Temperature last night was at -3o C and now it is -4o C it went down by 1 but dont forget the negative symbol.-1
you can think like this: -3-4=-1
The first one = 60.3 so it can’t be that one.
the second one = 34.5 so not that one either
the third one = 60.3
and the last one = 28.3
