a=9
This is a kite due to the adjacent congruent sides (shown by the tickmarks). With any kite, the diagonals are perpendicular. So angle 3 is 90 degrees.
<h3>Answer: 90 degrees</h3>
Based on the given, there are two ways to know the dimensions of the rectangle. First, by simply drawing the coordinates given in a cartesian coordinate plane, P1(0,6),P2(8,6) by looking at the ordinate the length is 6 units, thru P3 (0,0) and P4 (8,0) and looking at the abscissa, the width is 8 units. The second way is through the distance formula, d=sqrt (X2-X1)2+(Y2-Y1)2. The dimensions are L=8 and W=6
Answer:
The student should have switched the direction of the inequality sign to
get –5 > x for a final answer.
Step-by-step explanation:
When multiplying or dividing an inequality by a negative "flip" the inequality sign
The student should have switched the direction of the inequality sign to
get –5 > x for a final answer.
---------------
Note:
For a more conventional appearance the entire inequality can be flipped to
–5 < x
