The length of ST, the base of isosceles triangle ARST, can be represented by x. The length of one of its legs is 2x - 5. The perimeter of the triangle is 20. Given
ANOP = ARST, find the length of PN.
F. 6
G. 7
H. 8.33
J. 12.5
K. 14

Step-by-step explanation:

Are you using "A" to represent 225

? That's confusing. You are better off writing out "triangle."

Perimeter = 2(2x-5) + x  =  20

x = 6

length of base = 6 units

length of each leg = 7 units

Where is the illustration that shows △NOP ?

If PN is a leg, then its length is 7 units.

If PN is the base, then its length is 6 units.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

(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
