Step-by-step explanation:
Using similarity it can be solved as:
Answer:
PD = 12
Using the tangent ratio in right Δ PDW and the exact value
tan30° = , then
tan30° = = = = ( cross- multiply )
well .... 2 + 2 = 4
surface area
check
y intercept = (0,1)
x intercept = (1,0)
The simplest EXACT answer is .
A decimal form of this is approximately 5.207.
Use the distance formula.
