<u>Step-by-step explanation:</u>
x +
= 
need to eliminate the denominator:
x(8x) +
(8x) =
(8x)
8x² + 8 = 65x
8x² - 65x + 8 = 0
(8x -1)(x - 8) = 0
(8x -1) = 0 (x - 8) = 0
x =
x = 8
Answer:
The hight length : h
The base length : a

h² = 13² - (10/2) = 144
h = √144 = 12 cm
S = (a x h)/ 2 = ( 10 x 12 )/2 = 60 cm²
