Question not well presented and diagram is missing
Quadrilateral WILD is inscribed in circle O.
WI is a diameter of circle O.
What is the measure of angle D?
See attached for diagram
Answer:
Step-by-step explanation:
Summation of opposite angles of a quadrilateral inscribed in a circle is 180°, given that the vertices are on the circle.
Given
<WIL = 45°
<ILD = 109°
In the attached;
<WIL + <WDL = 180° (Opposite angle of quadrilateral)
Substitute 45° for <WIL in the above expression
45° + <WDL = 180° ---- Collect like terms
<WDL = 180° - 45°
<WDL = 135°
Hence, the measure of angle D is 135° (See attached)
Answer:
Christopher can take 56 different groups of 5 shirts.
Step-by-step explanation:
Christopher has 8 unique shirts.
Out of these only 5 can fit in his bag.
So the number of ways in which he can choose 5 shirts from the available 8 is given by
This can be evaluated as
Simplifying further,
=
= 56
So Christopher has 56 choices to select 5 shirts out of 8.
