Answer: -v^2 + 8v + 401
Step-by-step explanation:
You can use photomath it will give you the exact steps
-9-4d=3+8b first combine like terms so add 4b on both sides so its
-9=3+12b next subtract three on both sides
-12=12b next divide 12 on both sides
-1=b
Well there is 13 possibilities so it would be 10/13
Answer:
Option 2) 82°
Step-by-step explanation:
The dilation means the enlargement of the figure or reduction in the size of the figure.
If the scale factor is greater than 1, its an enlargement
If the scale factor is smaller than 1, it is a reduction.
But what ever be the case,
the triangles always remain similar.
Hence the size of the sides changes,
But the size of the angles always remains the same.
Now the largest angle of triangle ABC is 82°.
Hence the largest angle of the triangle DEF shall be 82°.
Second option 82° is the right answer.
