2e:3t+15=2e:6t
15=3t
t=5

In a right triangle the lengths of the legs are a and b. Find the length of a hypotenuse, if: a=3, b=4;
prohojiy [21]

Answer:

The hypotenuse is 5

Step-by-step explanation:

We can use the Pythagorean theorem to find the hypotenuse of a right triangle

a^2 +b^2 =c^2 where a and b are the legs and c is the hypotenuse

3^2 +4^2 =c^2

9+16=c^2

25=c^2

Take the square root of each side

sqrt(25) =sqrt(c^2)

5 = c
