Answer:
A. 72° .
B. 108°.
C. 72°.
D. 108°
Step-by-step explanation:
A =
18° + x = 90°
= 90° - 18 °
= 72°.
Therefore A = 72°
B =
As A and B lies on same line their sum will be 180°
Then A + B = 180°
72° + x = 180 °
180° - 72° = x
= 108°
Therefore B = 108°
C =
As B and C lies on same line their sum will be 180°
Then B + C = 180°
108° + x = 180°
180° - 108° = x
= 72°
Therefore C = 72°
D =
As sum of interior angles of rectangle is 360.
Then A + B + C + D = 360°
72° + 108°+ 72°+ D = 360°
252° + D = 360°
360° - 252° = D
= 108°
Therefore D = 108°
To recheck we can add
A + B + C + D = 360 °
72 ° + 108° + 72° + 108° = 360 °
Hence Proved !!!
