Quadrilateral ABCD is inscribed in a circle. Angle B measures 19°. What is the measure of angle D?
kherson [118]

Answer:

D = 161^o

Step-by-step explanation:

Given

\angle B = 19^o

Required

Find D

The label of the quadrilateral are not clear. However, a more complete question illustrates that B and D are opposite sides.

To solve for D, we make use of:

B + D = 180^o ---- opposite sides of a cyclic \\ quadrilateral

Make D the subject

D = 180^o -B

D = 180^o -19^o

D = 161^o

Please help me on this quick the work is due today
tester [92]

Answer:

1. 52 degrees 2. D

Step-by-step explanation:

1. The interior angles of a triangle add up to 180, so you can do 180 - 36 - 92 to find the third angle.

180 - 36 - 92 = 52 degrees

2. the angle XYZ has to equal the sum of the angles WXY and XWY. This means that 115 = 45 + XWY

115 - 45 = 72

XWY = D. 70 degrees

To determine whether a graph of a relation is also a function, Shayla declared that the Y axis is a vertical line and the counts
Inessa [10]
"No, because using the y-axis tests only whether x = 0 is mapped to multiple values." Shayla probably used the wrong method in finding whether the graph is a function or not.
