I would really appreciate anyone who can answer this attached question, thanks.

In an inscribed quadrilateral, opposite angles add up to 180°.

So ∠A + ∠C = 180°.

(3x - 10) + 2x = 180

5x - 10 = 180

5x = 190

x = 38

The opposite angles of a cyclic quadrilateral are supplementary.

A + C = 180 degrees

3x - 10 + 2x = 180

5x = 190

x = 38

38

We know A and C add to 180 because each is half the arc subtended, A=(1/2) arc BCD and C=(1/2) arc BAD.  The two arcs together are the entire circle so,

A + C = (1/2) arc BCD + (1/2) arc BAD

        = (1/2)(arc BCD + arc BAD) = (1/2)(360) = 180 degrees

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
