Question

Find the value of x in the triangle.​

Answer 1

• sum of angles in a triangle is 180
• let the angles be a, b, c
• angle of straight line is 180
• so, 120+a=180
• a=60

now,

• b+105=180
• b=75

since , a+b+c=180

c=180-(60+75)

c=75

in this question I considered x as c

hence x=75

MARK ME AS BRAINLIEST

Answer 2

Answer:

180-105 (linear pair)

=75

180-120 (linear pair)

=60

now with the help of ASP(angle sum property)

75+60+x=180

135+x=180

x=180-135

x=45
