I think that's what you mean
1.3n (it can be simplified like any other equation just add like terms and remember there is a one before every variable)
Movement by degree so by drawing it n tracing paper then rotating it a certain degree such as 90 degrees
it will be 8.25 hope this helped
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°
