ABCD is a trapezoid (AD∥ BC). BC = 5 cm, m∠ACD = m∠ABC = 90°, m∠BAC = 30°. Find the length of AD (the picture is not drawn to sc

lana [24]

Answer:

$AD=20\ cm$

Step-by-step explanation:

step 1

Find the length of AC

In the right triangle ABC

$sin($

we have

$m$

$BC=5\ cm$

substitute and solve for AC

$sin(30\°)=\frac{5}{AC}$

$0.5=\frac{5}{AC}$

$AC=10\ cm$

step 2

Find the length side AD

In the right triangle ACD

$cos($

we have

$m$

$AC=10\ cm$

substitute and solve for AD

$cos(60\°)=\frac{10}{AD}$

$0.5=\frac{10}{AD}$

$AD=20\ cm$
