Answer:
C
Step-by-step explanation:
Supplementary angles because their sum is 180 degrees
The first one would be $160 and the second one would be $525
Answer:
(- 1, - 1 )
Step-by-step explanation:
Since the dilatation is centred at the origin, then multiply the coordinates of the original point by the scale factor, that is
(- 3, - 3 ) → (
× - 3,
× - 3 ) → (- 1, - 1 )
<u>To find the area of a complex shape</u>:
⇒ must cut the whole shape into a simpler shape
- square with side lengths of 4 in
- 2 triangles with a base of 4 in. and a height of 8 in.
- 2 triangles with a base of 4 in. and a height of 10 in.
<u>Let's calculate:</u>
- Area of 2 triangles with a base of 4 in. and a height of 8 in.

- 2 triangles with a base of 4 in. and a height of 10 in.

- square with side lengths of 4 in

<u>Total Area</u>: 32 + 40 + 16 = 88 in²
<u>Answer: 88 in²</u>
<u></u>
