Question

find the value of x in following figure ​

Answer 1

Given:

angle ABC = 35°

angle CAB = 110°

angle BAC = x

To Find:

The value of x.

Angle Sum Property:

The sum of all the interior angles of a triangle is 180°.

Solution:

x + 110° + 35° = 180°

or, x + 145° = 180°

or, x = 180° - 145°

or, x = 35°

Answer:

The value of x is 35°.

Answer 2

Answer:

▪Sum of angles in a triangle is 180°

Consider triangle ABC,

<A+ <B+ <C =180°

110°+35°+x=180°

145°+x=180°

x=180°-145°=35°

▪x=35°
