Question

find the value of x by step by step explanation please i will make you brillineast. ....​

Answer 1

Answer:

hey! as per u wish i am explaining this step by step

Step-by-step explanation:

firstly, given is a pentagon

therefore, sum of the angles in pentagon is 540°

Now,

we also know that

for linear pair

x+y =180°

therefore

at left side

70+t=180 (t is assumed angle)

t=110°

at right side

60+k=180(k is assumed angle)

k=120°

therefore now

sum of angles

120°+110°+x+x+30°=540°

260°+2x=540°

2x=540°-260°

2x=280°

x=280/2

x=140°

hope it helps :)
