Hi does anyine know how to find the angle for this ?Please show working out.

X=30⁰

Step-by-step explanation:

Cos(x)=(s(6)+2×s(3))/(4+2×s(2))

Where s(..) = sqrt(..))

Cos(x)=s(3)×(s(2)+2)/(2×(2+s(2))=s(3)/2

Thus: x=30⁰

23

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
