Answer:
<h2>The missing value is 3, and the coordinates are (3,3).</h2>
Step-by-step explanation:
The complete question is

Complete the missing value in the solution to the equation. (3, ? )
By given, we know that
, because coordinates are written like
.
Then, we replace the given coordinate to find
.

Therefore, the missing value is 3, and the coordinates are (3,3).
Answer:
$69
Step-by-step explanation:
80 x 75% (0.75) = 60
60 x 15% (0.15) = 9
60 + 9 = $69
Since all triangles equal 180 degrees. You will subtract (128 + 23) from 180.
180 - 146 is 34 degrees.
x=34
