Question

find the value of x ​

Answer 1

Answer:

Step-by-step explanation:

Now,

$90 ^{\circ} + 90 ^{\circ} + 3x ^{\circ} + 80 ^{\circ} + (180-x) ^{\circ} = 540 ^{\circ}$

(The angle adjacent to x is 180-x (Using Linear pair))

Sum of all interior angles of a pentagon = $540 ^{\circ}$

Now solve this

440  + 2x = 540

2x = 100

x = 50°
