7n-8=3n+4. You subtract 3n in both sides and get 4n-8=4. then you add 8 to both sides and get 4n=12. Finally you divide both sides by 4 too get n by itself. n=3

Angle math Hw. Pls help
timurjin [86]

Answer:

x = 45°

Step-by-step explanation:

We can tell that "x + 115" and 160° are vertically opposite angles, which means that they are equal. (Refer to image)

⇒ x + 115 = 160

⇒ x = 160 - 115

⇒ x = 45°

How do you find the value for x in the problem?
Nata [24]
Make use of the fact that side lengths in similar triangles are proportional.
.. 30/18 = (20 +x)/20
.. 20*(30/18) -20 = x . . . . multiply by 20, subtract 20
.. 33 1/3 -20 = x . . . . . . . . evaluate the product
.. 13 1/3 = x
