Answer:
the third option: x + 2(2x - 4) = 10
Step-by-step explanation:
the question tells you that y = 2x - 4.
so, instead of writing y in the equation, just replace it with 2x - 4.
x - 2y = 10
becomes
x - 2(2x-4) = 10
ANSWER:
Distance between two points W and E = 146 miles and B is the position of B (balloon)
Angle BWE =55 degrees and angle BEW =67 degrees therefore angle WBE = 180-55-67 =58 degrees
Using sine formula
w/sin (55)= b/sin(58)
w= 146{sin 55/ sin 58) =141 miles Step-by-step explanation:
Answer:
30 degrees

Answer:
The ladder would reach 40ft
Step-by-step explanation:
The ladder forms a right angle triangle with the building and the ground. The length of the ladder represents the hypotenuse of the right angle triangle. The height that the ladder would reach along the side of the building represents the opposite side of the right angle triangle.
The distance from the bottom of the ladder to the base of the building represents the adjacent side of the right angle triangle.
To determine the height that the ladder would reach along the side of the building h, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
41² = 9² + h²
1681 = 81 + h²
h² = 1681 - 81 = 1600
h = √1600
h = 40 ft
