Answer 1

Let ABC be the DLet ∠A=x∠B=2x∠C=x∠A+∠B+∠C=1804x=180x=45∠A=45∠B=90∠C=45 .

Since ∠A=∠CABC is isosceles D 4 .

Since ∠B=90ABC is Right angled at B .

Answer 2

Answer:

total angle of a triangle= 180°

let the unknown angles be x

1:2:3 = 180 = x+x+x

${x}^{3} = \binom{180}{3}$

X = 60

60× 3 = 180
