Answer:
F) 4√3
Step-by-step explanation:
The altitude of the triangle creates a right triangle. The right triangle has a leg of 4 and a hypotenuse of 8. Using the Pythagorean theorem,
a²+4² = 8²
a²+16 = 64
Subtract 16 from each side:
a²+16-16 = 64-16
a² = 48
Take the square root of each side:
√(a²) = √(48)
a = √(16*3)
a = 4√3
a^2 + 4^2 = 8^2 --> a = 4·√3
Its good and yours? ill try to answer ur question i might not know lol
I dunno
Sorry
