Answer:
4,486.93 ft
Step-by-step explanation:
Let 'h' be the height of the mountain and 'x' be the horizontal distance between the first position measured and the top of the mountain.
Two right triangles can be modeled such that their tangent relationships yield:
Solving the linear system:
The mountain is 4,486.93 ft high.
Answer:
angle ZXY= 5x+8 = 5(13)+8 =73
angle ZXW= 7x-4= 7(13)-4=91-4=87 degrees
it is a
Step-by-step explanation:
add two angles together = 160
5x+8+7x-4=160
12x+4=160
12 x =160-4
x=156/12= 13
angle ZXY= 5x+8 = 5(13)+8 =73
angle ZXW= 7x-4= 7(13)-4=91-4=87 degrees
The type of reasoning that Vivian used into solving the
equation is the deductive. This type of reasoning is able to describe on how
the equation is done and this could be seen in the given scenario above as she
was able to show the steps in obtaining the correct answer.
Answer:
8r.
Step-by-step explanation:
If we substitute 3 into all of these equations, we get
8(3) which equals 24
6(3) which equals 18
9(3) which equals 27
7(3) which equals 21
8r is the one that equals 24 when 3 is substituted.
Answer:
178/7
Step-by-step explanation:
4x-7+3x+9=180
4x+3x-7+9=180
7x-7+9=180
7x+2=180
7x=180-2
7x=178
x=178/7
