Opposite angles in a cyclic quadrilateral are equal to 180°.
Therefore,
(4x+5) + (x+15) = 180°
Collect like terms
4x+x+5+15 = 180°
5x+20 = 180
5x = 180-20
5x = 160
x = \frac{160}{5}
x = 32

A = 4x+5
A = 4(32)+5
= 128+5
= 133°

I got 3.33 because I just set the problem up as

4x+5=x+15

and then I did

4x-x=3x

and then I did

15=3x+5

and then

15-5=10

and then

3x=10

then

10÷3=3.33

Ans: Option (D) 25%

Explanation:
In this case you need to find the area under the curve, which would essentially be the probability of a value in the sample space.

Now the range given is from 60 to 80; it contains the mini-triangle.

The area of the triangle = (1/2)*base*height

Since base = 80 - 60 = 20
Height = 0.025 - 0 = 0.025 (see in the graph)

Therefore
The area of the triangle = 1/4 = 0.25 which is essentially be the probability.

In percentage form, it is 25% (Option D)
