Question

find x in the given figure​

Answer 1

We know that the sum of all interior angles of a triangle is 180°

---> 48°+55°+3x+23=180°

---> 126°+3x=180°

---> 3x=54°

---> x= 54/3

---> x= 18°

Hope it helps you...✌️✌️

Answer 2

Answer:

Step-by-step explanation:

In the given triangle PQR,

P + Q + R = 180 (angle sum property)

48 + 3x + 23 + 55 = 180

126 + 3x = 180

3(42+x) = 180

42+x = 180/3

x = 60-42

x = 18
