Sagot :

Answer:

12.5

Step-by-step explanation:

We see in the other triangle that the ratios is 2:5 (4 to 10).

Therefore, assuming they are similar, we can assume the ratio is the same for the missing triangle.

So,

10/4 = 2.5

5(given) x2.5 =  12.5

Answer:

7.7

Step-by-step explanation:

10² - 4² = 84

√84 = 9.16 so 9.2

now we now have the hypotenuse of the other triangle

9.2² - 5² =59.64

√ 59.64 = 7.72 so 7.7
