Pete is solving for x in the problem to the right. He has decided that these angles are supplementary as 4x+16 is also the measure of the angle labeled with the star because of vertical angles. He then states that 7x-20 and the angle labeled star are same side interior, which he knows are supplementary. This leads to him solving for x and stating that the answer is 16.72. Is Pete correct? Explain your reasoning

Ascientist wants to use a model to present the results of his detailed scientific investigation. why would a model be useful? a )because the model makes the concepts easier to understand b) because the model is easy to put together and to use c) because the model prevents other scientists from asking questions d) because the model requires the audience to pay full attention to it i don't know what to choose because between a and d a is much more likely than d because it only wants to get the attention of the audience. i'm confuse.
