Since the quadrilateral is inscribed inside the circle, where the four vertices are on the circle itself, this means that the opposite angles add to 180 degrees.

Angle I and Angle D are opposite angles. They add to 180 degrees

(angle I) + (angle D) = 180
(45 degrees) + (angle D) = 180
(angle D) + 45 = 180
(angle D) + 45 - 45 = 180 - 45 ... subtract 45 from both sides
angle D = 135

The measure of angle D is 135 degrees

Lemur [1.5K]

Answer: There are 52 men we can expect to have been involved in a minor traffic accident.

Step-by-step explanation:

Since we have given that

Percentage of men has been involved in a minor traffic accident = 13%

Number of men surveyed = 400

So, Number of sample men we can expect to have been involved in a minor traffic accident is given by

\dfrac{13}{100}\times 400\\\\=0.13\times 400\\\\=52

Hence, there are 52 men we can expect to have been involved in a minor traffic accident.

The diagram shows a rectangle. The area of the rectangle is 310 m². Work out the value of w when 5x-9 is the length and 3x+7 is
Simora [160]

Answer:

w = 10

Step-by-step explanation:

First we take the two values for the breadth of the rectangle

So:

5x - 9 = 3x + 7

now we solve this equation as follows:

5x - 3x = 9 + 7

2x = 16

x = 8

now that we have found the value for x, we can substitute it in the equation, 5x - 9,or in the equation, 3x + 7.

when we substitute x in any of these equations, we get

5(8) - 9 = 31

3(8) + 7 = 31

now that we have the value for the breadth we can form the following equation:

31 × w = 310

31w = 310

w = 310/31 = 10
