Answer:
B = 612.2 ft
Step-by-step explanation:
Solution:-
- The elevation of person, H = 235 ft
- The angle of depression, θ = 21°
- We will sketch a right angle triangle with Height (H), and Base (B) : the boat's distance to the edge of the cliff and the angle (θ) between B and the direct line of sight distance.
- We will use trigonometric ratios to determine the distance between boat and the edge of the cliff, using tangent function.
tan ( θ ) = H / B
B = H / tan ( θ )
B = 235 / tan ( 21 )
B = 612.2 ft
The answer is C. 50 in, 48 in, 14 in
In a right triangle, a² + b² = c², where c is the longest side (hypotenuse), a and b are the other two sides.
14² + 48² = 196 + 2304 = 2500
50² = 2500
Answer:
y=2x−7
Step-by-step explanation:
so
formula is (
y
1
−
y
=
m
(
x
1
−
x))
m is the slope
-1-y=2(3-x)
add 1 to both sides
−y−1+1=−2x+6+1
−y=−2x+7
divide both sides by -1
y=2x−7

Answer:
(½x+½y)²=6
Step-by-step explanation:
x^2 + y^2 = 14, xy=5
(A+B)^2=A^2 +2AB+B^2... (*)
(1/2x+1/2y)^2 =(*)
(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =
1/4x^2 +1/2xy+1/4y^2=
1/4(x^2 +y^2) +1/2(xy)=
1/4*14+1/2*5=
14/4+5/2=
14/4+10/4=
24/4=6
