Question

Q1.Find the value of the unknown x in the following diagram:

Answer me in step by step explanation!​

Answer 1

Answer:

angle sum property of triangle is 180⁰

110⁰ + 30⁰ + X = 180⁰

140⁰ + X = 180⁰

X = 180⁰-140⁰

X = 40⁰

Answer 2

Simple question, just apply the Angle sum property of triangle,

i.e., sum of all the angles of a triangle = 180⁰

=> Angle ( X + Y + Z )= 180⁰

${30}^{0} + {110}^{0} + x = {180}^{0} \\ = > {140}^{0} + x = {180}^{0} \\ = > x = {180}^{0} - {140}^{0} \\ x = {40}^{0}$
