Answer 1

Answer:

sorry but I don't

my class is 5th

Answer 2

Answer:

108°

Step-by-step explanation:

in the given figure:-

angle 1 = (2a+b)°

angle 6 = (3a-b)°

we know, angle 6 = angle 2 as they are corresponding angles.

do, angle 2 = (3a-b)°

We can clearly see that angle 1 and 2 are supplementary angles and they both when added , add up to 180°

=>(2a+b)+(3a-b)=180 ------>(equation number 1)

=>5a = 180

=> a = 36°

hence the value of a is 36°

therefore, by substituting the value of a in equation 1 we get :-

=>(2×36 + b)+(3×36 - b) = 180

=>72+108+0b = 180

=>0b = 0

=>b=0

therefore, by substituting the values of a and b in angle 2 , we get :-

angle 2 = (3a-b)°

=108°-0°

=108°

hope it helped

thanks
