Question

Me ajudem a resolver . Urgente

Answer 1

(Ac)²=(ab)²+(bc)²
(Ac)²=(8)²+(6)²
(Ac)²=64+36
Ac=10
-------------------------------------
senÂ=(bc)/(Ac)
senÂ=6/10
=3/5
----------------------------
cosÂ=(ab)/(Ac)
=8/10
=4/5
------------------------
tgÂ=(bc)/(ab)
=6/8
=3/4
----------------
SenC=(ab)/(Ac)
=8/10
=4/5
--------------
cosC=(bc)/Ac
=6/10
=3/5
-------------
tgC=(ab)/(bc)
=8/6
=4/3
