iVinArrow [24]

Answer:

x = 4

Step-by-step explanation:

the segment inside the triangle is an angle bisector and divide the opposite side into segments that are proportional to the other two sides, that is

\frac{x}{x+4} = \frac{x+6}{2x+12} = \frac{x+6}{2(x+6)} = \frac{1}{2} ( cross- multiply )

2x = x + 4 ( subtract x from both sides )

x = 4

Eddi Din [679]

Answer:

35%

Step-by-step explanation:

To figure out the percentage of bronze medals, we must figure out the percentages of the gold and silver medals first.

We already know that 45% of the medals were silver.

We know that 4 of the 20 medals were gold.

4/20 as a percentage would be 20/100, or 20%.

So, 20% of the medals were gold, and 45% of them were silver.

45% + 20% = 65%

100% - 65% = 35%

So, 35% of the medals awarded were bronze.
