Question

please help me in finding value of x​

Answer 1

Answer:

60+ <BCD = 180

<BCD = 120

50 + <EDC = 180

<EDC = 130

<BAE + <BCD + <EDC + x + x = 540

40 + 120 + 130 + 2x = 540

290 + 2x = 540

2x = 540 - 290

2x = 250

x = 125°

Hope it will help you

Answer 2

formula for angle sum of pantagon = 180 ×(n−2) degrees, where n is number of sides

answer

The interior angles of the base of the pentagon will be 180-60= (120) and 180-50=(130)

angle sum of Pentagon = 180×(5-2) {n = 5 sides}

=180×3 = 540

120+ X + 40+ X +130 = 540

290+2x = 540

2x=540-290

2x= 250

x = 250÷2

x= 125
