Answer:
Step-by-step explanation:
Given
Represent point A as thus;
Required
Determine the new position of A, when rotated counterclockwise
The new position will be denoted as A'
When a point is rotated counterclockwise, we start by switching the positions of x and y as follows:
Then, y is negated to give A'
Answer:
120 6th graders
Step-by-step explanation:
You need to set up a proportion...
2/3= x/180
360=3x
x=120
Answer:
x=64°
Step-by-step explanation:
x=180-90-26 (angles on a str line)
=64°
S is 27. SRT is 63 becuase of the vertical angles theorem. All angles of a triangle add up to 180, and you already have the other two angles. So its 27
