just a little typo but 20/5 is 4

so the answer is 10

ok so if we find the first term...

we calculate the absolute value first so it is 4.2 and then floor it, giving us 4

for the second term, it is -5 because that is what the floor of -4.2 is... the absolute value of -5 is 5

4 + 5 = 9

since BC is 118, that means that A is 59 degrees because of the inscribed angle theorem (i think thats the right theorem).

add A and C, which is 59 + 48, which is 107

since triangle angles add to 180, 180 - 107 is 73

because of the inscribed angle theorem again, AC is 146

so if pedro is p, and ricky is r...

p + r = 2690

p = r + 284

therefore...

2r + 284 = 2690

2r = 2406

r = 1203

this means that

p = 1203 + 284 = 1487

p = 1487

r = 1203

if we double check this...

1487 + 1203 = 2690
