Ответ:
tanC = 3/4
Step-by-step explanation:
by Pythagoras theorem first find the line DE =
-> DE=27
then we know that tanθ=opposite/adjacent
so, 27/36 =tanC
simplified: tanC = 3/4
Ответ:
area=60
height=12
60=1/2 times base times 12
divide both sides by 12
5=1/2 times base
multipy both side sby 2
10=base
10 units=base
