Given: AB = 6, AD = x, CD = 16, and CB = 12.

What is the value of x?

Given:

AB = 6, AD = x, CD = 16, and CB = 12.

To find:

The value of x.

Solution:

Consider the below figure attached with this question.

In the figure BD is the angle bisector. So, using angle bisector theorem, BD divides the opposite sides in the ratio of other two sides.

Multiply both sides by 16.

Therefore, the value of x is 8.

the temperature will be -18 just do 62 + (-40) + (-40)

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
