Which of the following is equal to the expression listed above?
MA_775_DIABLO [31]

Answer:

(14 + 7) + 12 = 14 + (7 + 12)

Step-by-step explanation:

Given

(14 + 7) + 12 --- [Missing in question]

Required

Select equivalent expression

(14 + 7) + 12

Associative property states that:

(a + b) + c = a + (b + c)

In this case:

a = 14

b = 7

c = 12

So, we have:

(a + b) + c = a + (b + c)

(14 + 7) + 12 = 14 + (7 + 12)

B. is correct

The height of the mountain estimated by two students is 2,467.98 meters.

<h3>Height of the mountain </h3>

The height of the mountain is calculated as follows;

tanα = h/( a + b + x)

where;

  • x is the distance between end of b and h

tan37 = h/(1850 + 740 + x)

tan37 = h/(2590 + x)

h = tan37(2590 + x)

h =1,951.82 +  0.7536x  ---- (1)

tanβ = h/(b + x)

tan60 = h/(740 + x)

h = tan60(740 + x)

h = 1,281.68 + 1.732x ---- (2)

Solve (1) and (2) together

1,951.82 +  0.7536x = 1,281.68 + 1.732x

1,951.82  -  1,281.68 = 1.732x  -  0.7536x

670.14 = 0.9784x

x = 684.93 m

h = 1,281.68 + 1.732x

h = 1,281.68 + 1.732(684.93)

h = 2,467.98 m

Thus, the height of the mountain estimated by two students is 2,467.98 meters.
