Question

calcule os valores de C,R,X, e Y do triângulo

Answer 1

r² = (√7)² + (3√2)² 
r² = 7 + 18 
r = √25 
r = 5 
------------------------
5x = (√7)²
5x = 7 
  x = 7/5 
  x = 1,4 
------------------------
5y = (3√2)² 
5y = 18 
  y = 18/5 
  y = 3,6 
-----------------------
5c = (√7) × (3√2) 
5c = 3√14
  c = 3√14/5
