Answer:

see explanation

Step-by-step explanation:

(1)

The sum of the 3 angles in a triangle = 180° , thus

a + b + c = 180

(2)

adjacent angles are supplementary, thus

b + d = 180

(3)

From (1) and (2)

b + d = a + b + c ( subtract b from both sides )

d = a + c

In the figure below, PDW and WTC are right triangles. The measure of WPD is 30°, the measure of WC is 6 units, the measure of WT

aliya0001 [1]

Answer:

PD = 12 $\sqrt{3}$

Step-by-step explanation:

Using the tangent ratio in right Δ PDW and the exact value

tan30° = $\frac{1}{\sqrt{3} }$ , then

tan30° = $\frac{opposite}{adjacent}$ = $\frac{WD}{PD}$ = $\frac{12}{PD}$ = $\frac{1}{\sqrt{3} }$ ( cross- multiply )

PD = 12 $\sqrt{3}$
