<h3>34.61</h3>

Step-by-step explanation:

Find the diagram attached

From the diagram;

Hypotenuse = 81.9

Angle of elevation = 65degrees

Required

The value of x (Adjacent)

Using the SOH CAH TOA identity

cos theta = adjacent/Hypotenuse

cos 65 = x/81.9

x = 81.9cos65

x = 81.9(0.4226)

x = 34.61

Hence the value of x to the nearest hundredth is 34.61

Find two consecutive even interferes such that 4 times the smaller is 18 more than 3 times the larger.
Artemon [7]

The numbers are 24 and 26

Step-by-step explanation:

  • Step 1: Let the integers be x and (x+2). Here the smaller integer is x and the larger integer is x + 2.

Given that 4x = 18 + 3(x + 2)

⇒ 4x = 18 + 3x + 6

⇒ 4x = 24 + 3x

⇒ x = 24 and x + 2 = 26

chubhunter [2.5K]

Answer:

Option (C)

Step-by-step explanation:

The given graph represents the relation between her profit and the price charged.

x-intercepts from the graph are at,

x = 20 and x = 65, which show the selling prices.

x-intercepts means y = 0

And y = 0 represents no profit no loss.

When we summarize these data,

zeros : x = 20 and x = 65

These are the selling prices that will give her neither profit nor loss.

Therefore, Option (C) will be the answer.
