Question

Preciso de ajuda nos triângulos

Answer 1

Resposta:

a) x = 32  e  y = 19,5

b) x = 4,3    e   y ≅ 4,0

Explicação passo a passo:

a)                      

$\frac{24}{x} = \frac{15}{20}\\15x = 20.24\\x = \frac{480}{15} \\x = 32$  

$\frac{24}{32} = \frac{y}{26}\\32y = 24.26\\x = \frac{624}{32} \\y =19,5$

b)

$\frac{13}{y} = \frac{15}{5} \\15y = 13 . 5\\y = \frac{65}{15} \\y = 4,3$

$\frac{13}{y} = \frac{12}{x} \\\frac{13}{4,3} = \frac{12}{x} \\13 x = 4,3 . 12\\x = 4$
