Find the missing side<br> 13 ft<br> 5 ft <br> x
Scilla [17]

Answer:

Assuming you're referring to the sides of a right triangle, the missing side X would be 12.

Step-by-step explanation:

The Pythagorean Theorem states that the two legs of a right triangle squared and added together is equal to the hypotenuse squared. 13^{2} is 169, 5^{2} is 25, 169 - 25 = 144. Take the square root of 144 and you'll get 12, which is the missing side of the right triangle.

Country ​A, Country​ B, and Country C won a total of 130 medals. Country B won 10 more medals than Country C. Country A won 38 m
snow_lady [41]

Answer:

Country ​A = 84

Country​ B = 28

Country C = 18

Step-by-step explanation:

Country ​A, Country​ B, and Country C won a total of 130 medals;

A + B + C = 130 ......1

Country B won 10 more medals than Country C;

B = C + 10 .......2

Country A won 38 more medals than the total amount won by the other two;

A = B + C + 38 ........3

Substituting equation 3 to 1;

(B+C+38) + B+C = 130

2B + 2C + 38 = 130 .......4

Substituting equation 2 into 4;

2(C+10) + 2C + 38 = 130

4C + 58 = 130

4C = 130-58 = 72

C = 72/4 = 18

B = C + 10 = 18 + 10 = 28

A = B + C + 38 = 18 + 28 + 38 = 84

Country ​A = 84

Country​ B = 28

Country C = 18
