Answer:

x = \sqrt{21}

Step-by-step explanation:

AC² = AB² + BC²

BC² = 3² + x² = 9 + x²

AB² = 7² + x² = 49 + x²

But AC² = (7 + 3)² = 100

∴ 100 = 49 + x² + 9 + x²

2x² + 58 = 100

x² = 50 - 29 = 21

x = \sqrt{21}

erica [24]

Answer:

The answer is -32.

Step-by-step explanation:

Since there is no detailed information given about the game or the total tosses in the question, i will assume that the game is concluded when each player has had 4 tosses.

Considering the information that Reva missed the board 4 times out of her total 4 tosses in the game and each miss results in -8 points, her total score for those 4 tosses should be -8x4 = -32.

I hope this answer helps.
