I hope this helped you a lot

Answer 2

Answer:

40°

Step-by-step explanation:

Given: <a=100° <b= < c

To find: <b and <c

Solution:-

<a+ <b+ <c = 180°.....( sum of measure of all angles is supplementary)

:. 100° + <b + <b =180°...(b=c)

:. 100°+ 2(<b) = 180°

:. 2(<b) =180°-100°

2(<b)= 80°

<b = 80/2

*<b= 40°*

And, we know that <b= <c(from given)

:. <c = 40°
