Question

determine quantos graus tem cada angulo central indicado nas circunferências me ajudem pffvv ​

Answer 1

Resposta:

${19x\over\over3}+12x-4+4x+8x=360^{\circ}\\ \\ {19x\over3}+24x-4=360\\ \\ mmc=3\\ \\ 19x+72x-12=1080\\ \\ 91x=1080+12\\ \\ 91x=1092\\ \\ x=1092\div91\\ \\ x=12$

Vejamos as medidas dos ângulos

${19x\over3}={19.(\not12^4)\over\not3}=19.(4)=76^{\circ}\\ \\ 12x-4=12.(12)-4=144-4=140^{\circ}\\ \\ 4x=4(12)=48^{\circ}\\ \\ 8x=8.(12})=96^{\circ}$
