Question

Nos triangulos retangulos em a determine as medidas. E determine medidas pedidas e determine a area e perimetro do triangulo abc

Answer 1

a) b2 = a • m
( 6 ) 2 = 4a
36 = 4a
a = 36 / 4
a = 9

a = m + n
9 = 4 + n
4+ n = 9
n = 9 - 4
n = 5

c2 = a • n
c2 = 9• 5
c2 = 45
c = √45
c = 3√5

h2 = m•n
h2 = 4•5
h = √20
h = 2√5

b) m + n = 20
7 + n = 20
n = 20 - 7
n = 13

h2 = m• n
h2 = 7• 13
h2 = 91
h = √91

b2 = a •m
b2 = 20•7
b2 = 140
b = √140
b = 2√35

c2 = a• n
c2 = 20•13
c2 = 260
c= √260
c = 2√,65
