Question

find the value of x,yandz​

Answer 1

Answer:

(b) x=60°

(d) x =125°

Step-by-step explanation:

solution solution for question b is-

angle A =angle C(opposite angle of a parallelogram are equal)

angle C =60°

so, angle A=60 °

angle B =angle D (opposite angle of a parallelogram are equal)

so, 60°+x = 120°

x =60°

show the value of x =60°

solution for question d is

angle bcd + 60° =180° ,(linear pair)

so ,angle bcd =120°

angle cde +50°=180° (linear pair)

so,angle cde =130°

so now we know that the all interior angle of a pentagon add up to 540°

so, 40°+x+x+130°+120° = 540°

2x=250°

x=125°
