Answer:
Hey there!
These would also be acute angles.
Let me know if this helps :)
<span>42=-2d+6
Here, to find d, you need to separate it on one side.
First, subtract 6 from both sides.
42-6 = -2d + 6 - 6
36 = -2d
Now divide both sides by -2.
36/-2 = -2/-2d
-18 = d
The answer to this problem is -18, or d = -18.</span>
Answer:
The triangle could be a right triangle.
Step-by-step explanation:
Right triangles have right angles. (90 degrees). All triangles have 3 angles that add up to 180 degrees. So as long as one of the angles is 90 degrees, it's a right triangle.
I believe it is asking you to state if there’s any correlation between science and math test scores based on the graph.
Hope this helps!
