Answer:
25h+12
Step-by-step explanation:
Add the numbers :
21h-10h + <em>16</em><em>-</em><em>9</em><em> </em><em>+</em><em> </em>14h<em>+</em><em> </em><em>5</em>
21h-10h + <em>12</em><em> </em>+ 14h
Combine like terms:
25h + 12
Answer:
The image of the point is (1, 2)
Step-by-step explanation:
- If the point (x, y) rotated about the origin by angle 90° counterclockwise, then its image is (-y, x)
- If the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y)
- If the point (x, y) rotated about the origin by angle 270° counterclockwise, then its image is (y, -x)
Let us use the rules above to solve the question
∵ The point (-1, -2) is rotated 180° counterclockwise about the origin
→ By using the 2nd rule above change the signs of x and y coordinates
∴ Its image is (1, 2)
∴ The image of the point is (1, 2)
Answer:
the correct answer is option C) 0
Hope that helps! :)
Step 2 is wrong and i don't know the other question
Answer:
22.5 degrees
Step-by-step explanation:
Complementary angles add up to be 90 degrees. You can model the simple equation
where is x is the small angle and 3x is the large angle.

the smaller angle is 22.5 degrees
