Question

Find angle x, in the given figure.
​

Answer 1

180°-125( linear pair)

55°

now, X+90°+55°=180°( angle sum property)

X+145°-180°

X=180°-145°

X=35°ans.

Answer 2

Solution!!

Mark the angle y as shown in the attachment.

125° + y = 180° (Linear Pair)

y = 180° - 125°

y = 55°

Now one angle of the triangle is y. The second angle is x. The third is a right angle which means it is 90°. This also means that it is a right angled triangle.

The sum of the angles of a triangle is always 180°. This is the angle sum property of a triangle.

x + y + 90° = 180° (Angle sum property)

x + 55° + 90° = 180°

x + 145° = 180°

x = 180° - 145°

x = 35°
