Answer:
x=15°
Step-by-step explanation:
Angles ∠2 and ∠4 are supplementary, so ∠2+∠4=180°
That equals to 2x+10+4x+80=180.
You can solve that equation to find what <em>x</em> is equal to.
2x+10+4x+80=180
6x+90=180
6x=90
x=15°
Well 7x10^-5 would mean you moved the decimal 5 Times because the power at the end of 10 is how many times the decimal is moved till it’s a number greater or equal to 1. So the scientific notation of that is: 0.00003
The -5 means that it was moved to the right. Positive always means left. Negative is always right.

Answer:
13-4n
Step-by-step explanation:
The generic formula to calculate this is. a+(n-1) d
“a” is the first term and “d” is the difference in our case “a” is 9 and “d” is -4
9+(n-1)(-4)
9-4n+4
13-4n
