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 $m\angle ADB = 59\°$ .
