The sum of the measures of the interior angles in a polygon is 540 degrees. How many sides does the polygon have?

2 answers:

5 0

To find the answer you need to use the formula (n-2)180=sum with n being the number of sides of the polygon.
(n-2)180=540
180n-360=540
180n=900
n=5
so the polygon has 5 sides

U-3/4=4 please help me ty

Ne4ueva [31]

To solve the equation:

$\frac{u - 3}{4} = 4 \\ \frac{u - 3}{4} \times 4 = 4 \times 4\\ u - 3 = 4 \times 4 \\ u - 3 + 3 = 16 + 3 \\ u = 16 + 3 \\ u = 19$

Therefore, the answer is u=19.

Hope it helps!

Answer:

x = 6

Step-by-step explanation:

All triangle angles add up to 180 so:

90 + 5x + 6 + 54 = 180

5x + 150 = 180

5x = 30
