the picture below shows the path that puppy Liz is running. The electrical post is 40 feet tall. Puppy liz usually starts at the
anzhelika [568]

Puppy Liz has to run approx 70ft to get to fire hydrant from the bench post.

Step-by-step explanation:

Let bench post be point A, fire hydrant be B and electrical post bottom be C and top be O.

We are given CO = 40ft

and angle BOC = 34°

angle AOC = 34 +23 = 57°

Let AB be y and AC be x

Clearly two right triangles are formed.

We can say,

In triangle BOC,

cos34° = Perpendicular ÷ Base = x÷40 => x = 40cos34°

and In triangle AOC

cos57° = Perpendicular ÷ Base = (x+y)÷40

substituting value of x from first equation to second we get,

40cos57° = 40cos34° + y

y = 40(cos57° - cos34°)

y = 40x1.75

y = 70ft which is the required answer.

The sum of three and seven times a number is -74. What is the number?
Dima020 [189]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Form an equation with 'x' as the unknown number

7x + 3 = -74

Subtract 3 from both sides:

7x = -77

Divide both sides by 7:

x = -11

The number is -11
