Quadrilateral ABCD is inscribed in this circle. What is the measure of angle C?

Shkiper50 [21]

Answer:

107 degrees

Step-by-step explanation:

For an inscribed quadrilateral, the opposite angles are supplementary. Thus, B+D = 180 and you can solve for x.

3x+9+2x-4 = 180

5x = 175

x = 35

Next, plug the x value into angle A.

2(35) + 3 = 73

Angle C is the supplement of this which is 180-73 = 107

A book sold 41,900 copies in its first month of release. Suppose this represents 8.1 percent of copies sold to date. How many co

Diano4ka-milaya [45]

The total number of copies that have been sold till date are: 517284

Step-by-step explanation:

Let x be the total number of copies sold

Then

41900 is 801 percent of x

This can be mathematically written as

$41900 = 8.1\%\ of\ x\\41900 = 0.081 * x\\x = \frac{41900}{0.081}\\x = 51728.9$

Rounding off to nearest whole number

517284

Hence,

The total number of copies that have been sold till date are: 517284
