I don’t understand this can someone help me?

f

Step-by-step explanation:

You know that:

X is congruent to angle Z which means they are the same size

the straight line below is equal to 180

Y is a right angle so its equal to 90

So that means:

if x and z are equivalent that means they are equal to 2x essentially

and if you add 90 you will get the total of the line

Hope this helps!!! :)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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
