Answer:
79.4
Step-by-step explanation:
Hello!
To find the length of a missing side of a right triangle we use the equation.
[tex]a^{2} +b^{2} =c^{2}[/tex]
a is one leg
b is the other leg
c is the hypotenuse
Put in what we know
[tex]a^{2} +38^{2} =88^{2}[/tex]
Simplify
[tex]a^{2} +1444 = 7744[/tex]
subtract both sides by 1444
[tex]a^{2} = 6300[/tex]
Take the square root of both sides
a = 79.372
Round to the nearest tenth
a = 79.4
Hope this helps!
