Question

Suppose angle A=angle B and angle B is supplementary to angle c. If angle c =66, find angle A

Answer 1

Answer:

Suppose angle A=angle B and angle B is supplementary to angle c. If angle c =66, find angle A

Step-by-step explanation:

180-66=b

180-66=a. (as a=b)

114=a

Answer 2

Since angel B is supplementary to angle C
Then angle B + angle C =180
Therefore, angle B + 66 =180
Therefore, angle B = 180-66
Therefore, angle B = 114
Then angle A = 144
Because angle A = angle B
Therefore, angle A =144
