Step-by-step explanation:
hello :
note :
note : distance between A(X1,Y1) an B (X2,Y2) is :
AB= √((X2 - X1)² + (Y2 - Y1)²) (given point B(2 , 3)
in this exercice : X1 = 2 X2 = ? Y1 = 3 Y2 = ? d=AB=5
d² = (X2 - 2)² + (Y2 - 3)² =25
the points are a distance of 5 units from B (2, 3) if d = 5 :
the points are located on a circle with center B and radius 5
Answer:
407.22 foot is the boat from the base of the lighthouse
Step-by-step explanation:
Given the statement: An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression.
Let x foot be the distance of the object(boat) from the base of the lighthouse
Angle of depression = 
[Alternate angle]
In triangle CAB:
To find AB = x foot.
Using tangent ratio:


Here, BC = 50 foot and 
then;

or


Simplify:
AB = x = 407.217321 foot
Therefore, the boat from the base of the light house is, 407.22'
Answer:
Kite properties include (1) two pairs of consecutive, congruent sides, (2) congruent non-vertex angles and (3) perpendicular diagonals. Other important polygon properties to be familiar with include trapezoid properties, parallelogram properties, rhombus properties, and rectangle and square properties.
Step-by-step explanation:
Divide 45 by three because it is 3:4 of the cost then mutiply it by four so e entire cost would be 60.
