Question

A triangle has base length of (x-2) cm and high of 8 cm. if its area is 104 cm, then hypotenuse is...

Answer 1

Alas = x-2
Tinggi = 8
Luas = 104
Maka,
1/2 at = 104
1/2 (x-2)8 = 104
4(x-2) = 104
x-2 = 26
x = 28

Didapat:
a = 26
t = 8
Sehingga,
Sisi miring:
= √26² + 8² = √676 + 64
= √840
= 2√210 cm
