(2x + 3) + 90 = 180 solve for x

your question:

(2x + 3) + 90 = 180 solve for x

(2x + 3) + 90 = 180 ~ remove the already reduced parenthesis

2x + 3 + 90 = 180 ~ add numbers together

2x + 93 = 180 ~ subtract 93 from both sides

2x = 87 ~ divide by two on both sides to find x

x = 43.5

x = 43.5 or x= 43 ½ (fraction form)

Hope this helps, have a great day! :)

(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

probably the last option
