Use the diagram, which is not drawn to scale to find AD if you know that AC=24 & BC=12
Firdavs [7]

Answer:

Option b. AD=18\ units

Step-by-step explanation:

step 1

In the right triangle ABC

<em>Find the sine of angle CAB</em>

sin( ---> the sine of angle CAB is equal to divide the opposite side angle CAB (BC) by the hypotenuse (AC)

substitute

sin(

simplify

sin( ---->equation A

step 2

In the right triangle BDC

<em>Find the sine of angle CBD</em>

sin( ---> the sine of angle CBD is equal to divide the opposite side angle CBD (DC) by the hypotenuse (BC)

substitute

sin( ----> equation B

step 3

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

Triangles ABC and BDC are similar by AA Similarity Theorem

therefore

m∠CBD≅m∠CAB

equate equation A and equation B

\frac{DC}{12}=\frac{1}{2}

solve for DC

DC=\frac{12}{2}=6\ units

step 4

Find the value of AD

AD=AC-DC

substitute the values

AD=24-6=18\ units
