under square root of 50 ()

Step-by-step explanation:

Use pythagorean theorem. a^2 + b^2 = c^2. 5^2 is one leg, the other leg is also 5^2, and the x is what we need. So 5^2 is 25. 25 + 25 is 50. Thus, x is  (or under square root of 50), which is our answer!

(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
