How do you answer this?

x = -

Step-by-step explanation:

Using the rules of exponents

=

⇔

Note that 16 = 4² and 64 = 4³ , then

= , can be expressed as

= , that is

=

Since the bases on both sides are equal, then equate the exponents

2x = - 3 ( divide both sides by 2 )

x = -

e) none of the above because the measure of angle cba is 101°

(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
