Question

A 75 DEGREE
B 81 DEGREE
C 50 DEGREE
D 60 DEGREE​

Answer 1

Answer:

$\sf \: option \: c$

In this figure it is an isosceles triangle.

$\rm \: so \: the \: answer \: is : \red{50°}$

Angle x = 50°

it is an isosceles triangle.

the total sum of a triangle = 180°

∴ 50° + 50° + third angle = 180°

⇒ 100° + third angle = 180°

⇒ third angle = 180° – 100° ⇒ = 80°

⇒ 50°+50°+80°=180°

Answer 2

Step-by-step explanation:

In this figure it is an isosceles triangle.

$\color{darkorange}\rm \: so \: the \: answer \: is : \color{violet}{50°}$

∠x = 50°

it is an isosceles triangle.

the total sum of a triangle = 180°

∴ 50° + 50° + third angle = 180°

⇒ 100° + third angle = 180°

⇒ third angle = 180° – 100° ⇒ = 80°

⇒ 50°+50°+80°=180°
