What mistake did Antonio make?

The theorem he used is the SAS (side-angle-side) theorem. The diagram actually depicts 2 sides and 1 angle, but the angle is not sandwiched by the sides, meaning it would be a SSA, not SAS.

Step-by-step explanation:

For Antonio to be correct, the angle would have to be between the two given side lengths, so it would have to be angle A or angle T.

step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
