Question

Na figura abaixo, determine as medidas x e h indicadas.

Answer 1

Temos:

h²+x²=25²
h²+x²=625
h²=625-x².......(1)

h²+(11+x)²=30²
h²=900-(11+x²).....(2)

(1)=(2)

625-x²=900-(11+x)²
625-x²=900-121-22x-x²
625=779-22x
22x=779-625
22x=154
x=154/22
x=7

Em......(1)
h²=625-7²
h²=625-49
h²=576
h=√576
h=24

Resposta:
x=7
h=24
