Question

In the given figure if a-b =80° find a and b.​

Answer 1

Step-by-step explanation:

given=a-b=80 degree

hence a=80 degree+b

b=b

then we get the equation now

equation=80 degree+b+b=180(linear pair)

=80 degree+2b=180

=2b=100 degree

b=50 degree

therefore a=80 degree+b

=80+50=130 degree

b=b

=50 degree

that means the value of a is equals to 130 degree and the value of B is equals to 50 degree.

thank u

have a nice day

hlo friend

u really name is tanisha ???

Answer 2

Answer:

Step-by-step explanation:

given : b - a = 80degree

a = b + 80

b + 80 + b = 180degree

2b = 180 - 80

2b = 100

b = 100/2

b = 50

a = b + 80

a = 50 + 80

a = 130degree
