Question

Va rog goarte repede....va rogggg....dau 55 puncte​

Answer 1

$m(<A)+m(<B)+m(<C)=180\\x+20+2x+\frac{x-16}{2} =180|*2\\2x+40+4x+x-16=360\\7x=24=360\\7x=336$

$x=\frac{336}{7} =48\\y=180-\frac{x-16}{2} \\y=180 -\frac{48-16}{2} \\y=180-\frac{32}{2} \\y=180-16 =164$

$m(<A)=68\\m(<B)=96\\m(<C)=16\\m(<ACD)=164$
