Question

Answer all these with process ​

Answer 1

${\mathbb{\purple{hOlA!!}}}$

Ans:-1:-
let the other angles of triangle be x and y

x+y=180°
[by asp]

x+y=180°-110°

x+y=70° --------1

x=y[opposite angle of isosceles∆]

x=x----------2

x+y=70°[from 1]
x+x=70°[from 2]

2x=70°

x=35°

${\boxed{x=y=35°}}$



Ans:-2:-


One angle =80°

y=80°{opposite angles of a paralleogram are equal}

80+x=180°[adjacent angles]
x=180°-80°
x=100°


x=z=100°{opposite angles of paralleogram are equal}





Ans:-3:-

Sum of angles=120°

Ratio=1:2

let the ratio be 1x and 2x

sum=1x+2x
120°=3x
x=${\frac{120}{3}}$

x=40°

Measure of angles:-

1x=1×40°

=40°

and

2x=2×40°

=80°
