Question

Find 'x' in the following figure? angle A 56 dgree and Angle B x degree and angle c 123 degree angle D​

Answer 1

Answer:

let take a quadrilateral ABCD

given that,

angle A =56°

angle B = x°

angle C = 123°

angle D = ?°

To find= value of x

sol^ :measure of angle A+ measure of angleD = 180°( opposite angle are supplymentary)

56°+D= 180°

D= 180°-56°

D= 124°

similarly,

measure of angleB+ measure of angle C=180(opposite angle are supplymentary)

x + 123° =180°

x = 180°-123°

x = 57°

.•. measure of angle B = x= 57°

Answer 2

Answer:

x=57°

Step-by-step explanation:

let take a quadrilateral ABCD

given =}

angle A =56°

angle B = x°

angle C = 123°

angle D = ?°

To find= value of x

measure of angle A+ measure of angle D = 180°( opposite angle are supplementary )

56°+D= 180°

D= 180°-56°

D= 124°

similarly,

measure of angle B+ measure of angle C=180(opposite angle are supplementary)

x + 123° =180°

x = 180°-123°

x = 57°

hope it helped you

have a good day
