30 degrees and 40 degrees and side measures of 5 cm, 7cm, and 8 cm. Explain, using sides and angles, which type of triangle Kevi
n drew.

Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
Two angles are given as 30 and 40 degrees.
The third angle we could find by subtracting both angles from 180.
So, third angle would be =
As we can see, there is no side which is equal to each other.
Similarly, there is no angle which is similar to each other.
Hence the triangle is Scalene triangle. : Answer
Hope it will help :)

I take it you meant θ angle, anyway.
we know the tan(θ) = -4/7... alrite, we also know that 270° < θ < 360°, which is another to say that θ is in the IV quadrant, where the adjacent side or "x" value is positive whilst the opposite side or "y" value is negative.
