Question

find the value of x if it is a right angle triangle (50° aldready given )​

Answer 1

Answer:

40°

Step-by-step explanation:

If it is a right angle triangle one of it's angle =90°

The sum of the angles in a triangle =180°

Therefore,180-[90+50]=180-140=40°

Answer 2

Answer:

$x = 40$

Step-by-step explanation:

x + 90 + 50 = 180

( sum of triangle is always 180 )

x + 140 = 180

x = 180 - 140

x = 40°
