Question

Type the correct answer in each box

Answer 1

by angle sum property in traingle having $\angle x$,

$50+70+x=180 \implies x=60^{\circ}$

now, by exterior angle property of triangle, $x+y=60+50$

put $x=60$ to get $y=50$

Answer 2

Here,

x+50°+70°= 180° [°.°Angle sum of triangle]

↪x= 180°-120°

↪x=60°

.°. x = 60°

Now,

Let z be the unknown angle of the second triangle

z+60°+50°=180° [°.° Angle sum of triangle ]

↪z=180°-110°

↪z=70°

. ° . z=70°

Then,

z+x+y= 180°

↪70°+60°+y=180°

↪y=180°-130°

↪y=50°

.°.y = 50°
