To solve this problem, we have to use this theorem

m\angle ADC=\frac{1}{2}m\angle\text{ABC}

Replacing the given angle, we have

\begin{gathered} 23=\frac{1}{2}m\angle ABC \\ m\angle ABC=46 \end{gathered}<h2>Hence, the angle ABC is equal to 46°.</h2>

Westkost [7]
Since quadrilaterals have interior angles that add up to 360, then subtract the known values from 360

360 - 90 - 90 - 146 = 64

Angle C = 64

Identify the two tables which represent quadratic relationships. x 0 1 2 3 y -4 -8 -10 -10 x 0 1 2 3 y 4 -4 -4 4 x 0 1 2 3 y -2
Vitek1552 [10]

To estimate that table given in Option (4) will define the quadratic relationship.

Therefore, the table of Option (5) will describe the quadratic relationship.

<h3>How to estimate the quadratic relationships between two tables?</h3>

By estimating the second difference, if the second difference in a table exists equivalent, the table will define the quadratic relationship.

In the given option, we estimate that table given in Option (4) will define the quadratic relationship.

x       y      I st difference       II nd difference

0      4           -                               -

1      -4      -4 - (4) = -8                    -  

2     -4      -4 - (-4) = 0                0 - (-8) = 8

3      4       4 - (-4) = 8                 8 - 0 = 8

The second difference between the terms in y exists exactly as 8.

Therefore, the table of Option (4) means the quadratic relationship.

Similarly, in Option (5) we will estimate the second distinction of y terms.

x        y             I st difference       II nd difference

0      -4                     -                          -

1       -8               -8 - (-4) = -4              -

2     -10             -10 - (-8) = -2      -2 - (-4) = 2  

3     -10             -10 - (-10) = 0       0 - (-2) = 2

Here the second difference exists identical to 2.

Therefore, the table of Option (5) will describe the quadratic relationship.

Can someone give me an explanation for the right answer
Leno4ka [110]

if we notice in each triangle ∡A = ∡R and ∡ACW = ∡RWC, thus the angle tickmarks.

now, both triangles are sharing the side CW, so CW is the same length on each.

so we have, an Angle, then another Angle and then the Side, in common in each triangle, AAS.
