Answer:
Step-by-step explanation:
1. Translate (x, y) → (x + 1, y + 2)
The x coordinate will be translated 1 units horizontally and the y coordinate will be translated up 2 units vertically but they are still locate in the 1st quadrant
2. R (origin, 90° clockwise)
It still locate in the 1st quadrant because after rotating it will create an angle 90°
3. Translate (x, y) → (x + 2, y - 3)
The x coordinate will be translated 2 units horizontally but the the y coordinate will be translated down 3 units vertically, so:
- It will remain in the first quadrant.
- There is no size of the triangle will change.
Answer:
45°
Step-by-step explanation:
The angle with measure of 9x and the angle with measure of 3x are supplementary
9x + 3x = 180°
12x = 180 divide both sides by 12
x = 15
The angle with measure of 9x and angle a are supplementary as well
9x + a = 180
9×15 + a = 180
135 + a = 180 subtract 135 ftom both sides
a = 45°
