So to complete this you need to choose either sin cos or tan.

You know the hypotenuse and Ф but need to find the opposite.

So you would choose to use sin.

Opposite = sinФ * hypotenuse:
Opposite = sin43 * 13 = 8.9.

It would go 8.9 meters up the wall.

Find the value of x and y
Yakvenalex [24]

Answer:

x = 80, y = 122

Step-by-step explanation:

I got this equation by using vertical angles to create a complimentary angle pair (they sum to 90 degrees).

3/4x+2/5x-2=90°,

23/20x - 2=90°,

23/20x = 92°,

92/(23/20)

20/(1/4)

20(4)

= 80.

Since the angles are a linear pair on the left side(they sum to 180 degrees). Just subtract 180 from 3/4x-2 and substitute x into the expression.

180-(3/4(x)-2), 180-3/4(80)+2 = 120+2 = 122

7. The length of a rectangle is two more than its width. The perimeter of the rectangle is 36 feet. What are the dimensions (len
Reika [66]

Step-by-step explanation:

length = x + 2

width = x

x + x + (x+2) + (x+2) = 36 ft

4x + 4 = 36 ft

4x = 32 ft

x = 32 ÷ 4

x = 8 ft

dimensions = length x width

= (x+2) × x

= (8+2) × 8

= 10 ft × 8 ft

Answer:

Step-by-step explanation:

√14 cannot be rewritten as the ratio of two integers and thus is irrational.

Similarly, √99 is irrational; √99 = √9√11 is irrational even though √9 is not.
