Question

In the following figure, find the value of the unknown.

Answer 1

Answer:

(4b-21)°+(2b+1)°+(b+34°)+(3b-14)° = 360°

= 10b +35 - 35 = 360°

= b = 360°/10

= b = 36°

Answer 2

Answer:

b = 36

Step-by-step explanation:

In the figure we don't have any linear pairs or vertically opposite Angles.

But as total summation should be 360

Thus adding all for angles =

4b - 21 + 3b - 14 + b + 34 + 2b + 1 = 360

10b = 360

Thus b = 36
