I couldn’t type it so I just took a picture. Please help me!! I’ll give you 25 points!

It would be D.

Step-by-step explanation:

You have to collect like terms which would involve the 5 and -10 and do the same for the other 2

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

(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
