Question

find the value of x​

Answer 1

Answer:

70⁰, 120⁰

Step by step explanation:

1 . In triangle ABC,

X= 180⁰- (50⁰+60⁰)

= 180⁰- 110⁰

= 70⁰

2. X= 50⁰+ 70⁰

= 120⁰

Answer 2

Answer:

Step-by-step explananation;

angle sum propert of a triangle is 180 degree

First;

Triangle ABC

50degree + 60degree + x = 180

110degree +x = 180

x        = 180 - 110

x = 70degree

Second;

Let's take another triangle as DEF

D = 50 degree

E = 70 degree

F = x  ( interior)

find the angle of interior angle

50 degree + 70 degree + x = 180

130 degree + x = 180

x = 180 - 130

x = 50

now we  found the interior angle

now,

exterior angle x = 180 - 50 ( linear pair)

x = 130 degree
