Answer:
I was extremely angry my brother Buzz had eaten the last piece of cheese pizza!
Step-by-step explanation:
maybe just adding an exclamation point would be showing the emotion.
so maybe something along the lines of:
I was extremely angry at my brother Buzz when he told me he had eaten the last piece of cheese pizza!
.a good way to show rather than tell is to use specific, strong adverbs and use expressive dialogue to convey characters emotions and attitudes.
you can also use more expressive or exaggerated words, for instance rather than saying "I'm mad at you" ,you can say "I'm furious with you!" or "I'm extremely furious with you!"
hope this helped
