Mathematics
1 answer:
Vaselesa [24]3 years ago

Answer:

19.7ft

Step-by-step explanation:

Este problema é resolvido usando o teorema de Pitágoras (a2 + b2 = c2). Nesta fórmula, a e b são as pernas do triângulo retângulo, enquanto c é a hipotenusa.


Usando as etiquetas do nosso triângulo, temos:


o2 + a2 = h2


\ dpi {100} h ^ {2} = (10ft) ^ {2} + (17ft) ^ {2}

h2 = 100ft2 + 289ft2


h = 389ft2 −−−−− √


→ 19,7 pés

I’m really confused please help
Vikentia [17]

Answer:

(2). <em>b - (a + c)i </em>

Step-by-step explanation:

i^{7} = [( i )²]³ × i = ( - 1)³ i = - i

i^{16} = ((i)^2)^{8} = ( - 1)^{8} = 1

((i)^2)^{10} × i = i

a(- i ) + b( 1 ) - c( i ) = - ai + b - ci = <em>b - (a + c)i</em>
