Question

please answer my question​

Answer 1

Answer:

here,

       b = 45° (opposite angel of a parallelogram are equal)

now, a = c

     

so,

⇒ a + c + 45 + 45 = 360° (sum of all angels of a parallelogram is 360°)

⇒ 2a + 90 = 360°

⇒ 2a = 360 - 90

⇒ 2a = 270

⇒ a = $\frac{270}{2}$

⇒ a = 135°

hence, a = 135°

           b = 45°

           c = 135°

           d = 45°
