Cameron wants to measure a poster frame he only has a sheet of paper that is 8 1/2 x 11” he lays the long edge of paper along the long edge of the frame several times in fines that the frame is for papers long how long is this in inches

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

4400

step-by-step explanation:

coins of silver or gold

step-by-step explanation:

(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
