5n - 6 n
2n + 1
If the perimeter of this triangle is 15 centimeters, what is the value of n

1'/4

Step-by-step explanation:

perimeter of a triangle is a + b + c

15 = 5n+n+2n-6+1

15 = 8n - 5

15 - 5 = 8n

10 = 8n

n = 10/8

n = 1'/4

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

p = 6s
