Question

Find the missing angle in the following polygon

Answer 1

hey there!!

THe sum of the two angles is 70.

The other two angles are equal as shown in the picture.

total angle is 360

70 + x + x = 360

70 + 2x = 360

2x = 360 - 70

2x = 290

x = 145

Each ANglE is 145

Hope my answer helps!

Answer 2

YOUR ANSWER ⬇⬇⬇



_________________



angle B = angle D

Let angle B be x

then,

x + x + 40 + 30 = 360

2x + 70 = 360

2x = 360 - 70

x = 290 ÷ 2

x= 145

So,

the angle B = 145 degree and

angle D = 145 degree
