Question

find the value of x ​

Answer 1

To find :-

• The value of x

Solution :-

As we know that the sum of internal angle of triangle is 180 degree

So,

$= > 30 + 90 + x = 180 \\ = > 120 + x = 180 \\ = > x = 180 - 120 \\ x = 60$

Answer 2

Answer:

60°

Step-by-step explanation:

as sum of triangle is 180°

so 180 =90+30+x

180=120+x

x=180-120

x=60

therefore x=60°
