Answer:
<h2>The x-coordinate after the rotation is -10.</h2>Step-by-step explanation:
A 810° rotation is equal to a 90° rotation. So, the transformation described gives the same result than rotating 90° only.
A 90° counterclockwise rotation is defined by the rule
The given coordinate is . Using the rule, we have
Therefore, the x-coordinate after the rotation is -10.
Answer:
Option D
Step-by-step explanation:
32). Given vertices of the triangle are M(2, -3), N(3, 1) and O(-3. 1).
Distance between two points and
is given by the expression,
Distance =
Distance between M(2, -3) and N(3, 1) will be,
MN =
=
=
Distance between M(2, -3) and O(-3, 1),
MO =
=
=
Distance between N(3, 1) and O(-3, 1),
NO =
= 6
Condition for right triangle,
c² = a² + b² [Here c is the longest side of the triangle]
By this property,
MO² = MN² + NO²
41 = 17 + 36
41 = 51
False.
Therefore, given triangle is not a right triangle.
Since, length of all sides are not equal, given triangle will be a scalene triangle.
Option D is the correct option.
