Answer:
Option (D)
Step-by-step explanation:
Given quadrilateral in the circle is a cyclic quadrilateral.
By using the property of cyclic quadrilateral,
"Sum of each pair of opposite angles is 180°".
In the given cyclic quadrilateral,
d + 57° = 180°
d = 180 - 57
d = 123°
Similarly, c + 31° = 180°
c = 180° - 31°
c = 149°
Therefore, Option (D) will be the answer.
F(-1)=81+3e-.7(-1)
enter into scientific/ graphing calculator
f(-1)=89.85
4y + 10 =
2(2y + 5) <== factored form
The supplementary angle is 0.628.
Hope that helps
