BY the AA postulate, triangles ABC and APQ are similar.

In similar triangles, corresponding sides are proportional.

This means that
AB/AP = BC/PQ

Substituting values, 
AB=15
AP=15+7.5=22.5
PQ=18
=>
15/22.5 = x / 18
solve for x
x=18(15/22.5)=18(2/3)=12

Answer: x=12

Find angle ADB of the equation
Aloiza [94]

Answer:

m\angle ADB = 59\°.

Step-by-step explanation:

Given:

\angle BDC = 31\°

We need to find \angle ADB.

Solution:

Now we can see that given figure is a rectangle with diagonals drawn in it.

So by properties of rectangle which states that;

"All angles of a rectangle are 90°."

So we can say that;

\angle A = \angle B = \angle C = \angle D = 90\°

But

\angle D = \angle BDC + \angle ADB

Substituting the values we get;

31\°+\angle ADB = 90\°

Subtracting both side by  by 31 we get;

31\°+\angle ADB -31\°= 90\°-31\°\\\\m\angle ADB = 59\°

Hence m\angle ADB = 59\°.
