How do I solve this? It says find the value of x, then find the angle measures of the polygon.

Anni [7]

180 = 65 + (x-5) + x
-65 -65

115 = x - 5 + x

115 = 2x - 5

2x = 120

x = 60

The angle measures are 65, 60, and 55 degrees.

Which equation has a solution of n = 4?

Allushta [10]

Answer:

D. 7n = 28

Step-by-step explanation:

Let's substitute 4 for n in each equation to check if it the resulting equation is correct:

$6+n=24\\ 6+4=24\\ 10\neq 24\rightarrow \text{Incorrect!}$

$5n=54\\5(4)=54\\20\neq54\rightarrow\text{Incorrect!}$

$12-n=16\\12-4=16\\8\neq16\rightarrow\text{Incorrect!}$

$7n=28\\7(4)=28\\28=28\rightarrow\text{Correct!}$

Therefore the answer is D
