Question

find the value of x​

Answer 1

Answer:

$60 \degree$

Step-by-step explanation:

As we know that

The sum of all interior angles of a Quadrilateral is 360°

< A + < B + < C + < D = 360°

90° + 90° + x + 120° = 360°

x = 360° - 300°

x = 60°

Answer 2

$property \: to \: use \: . \: \: sum \: all \: of \: \\ all \: angles \: of \: quadrilateral \: is \: 360 ^{0} \\ \\ \: here \: {d}^{0} = {x}^{0} \\ according \: to \: above\: figure \: \\ \\ a \: + b + c + d \: = 360 ^{0} \\ 90 + 90 + 120 + d \: = 360 \\ = 300 + d \: = {360}^{0} \\ = d \: = 360 - 60 \\ d = 60 ^{0} \\ it \: will \: definetly \: help \: u...$
