Answer 1

Answer:

$<marquee>$

a = 11°

amd

b = 180° - 11°

b = 169 °

Answer 2

Given:

Angle a=11 degree

To find:

Angle  b

Solution:

Angle a+angle b=180 degrees

Reason: Linear pair sum

Substitute the values then we get

$11+\angle b=180$

$\angle b=180-11$

Using subtraction property of equality

$\angle a=169^{\circ}$

By simplification

Hence, the value of angle b=169 degree
