B. cdb ....angle cdb is adjacent to angle adb because they have a common side (line db)
Answer:
2
Step-by-step explanation:
Tan of an angle = perpendicular / base
<span>Here, perpendicular is the side of the triangle opposite the angle. </span>
<span>And base is the arm of the angle other the hypotenuse. </span>
<span>If the side of the triangle to be found (marked as ? in the figure) is x, then </span>
<span>perpendicular = 20 feet </span>
<span>base = x </span>
<span>so, tan 30 = 20/x </span>
<span>so, x = 20/(tan 30 degrees) = 34.64 feet </span>
<span>= 35 feet to the nearest foot</span>
Answer:
F = 
C + 32
Step-by-step explanation:
Given
C = 
(F - 32)
Multiply both sides by to clear the fraction
C = F - 32 ( add 32 to both sides )
C + 32 = F
