Answer:

15/17

Step-by-step explanation:

You can use what is called the Pythagorean identity:

sin(θ)² + cos(θ)² = 1

(-8/17)² + cos(θ)² = 1

cos(θ)² = 1 - 64/289 = 225/289

cos(θ) = √(225/289)

cos(θ) = 15/17 . . . . . . . cosine is positive in the 4th quadrant

An architectural drawing lists the scale as 1/4" = 1'. if a bedroom measures 312" by 514" on the drawing, how large is the bedro

The length of the bedroom exists at x = 9 and y = 6.

<h3>How to estimate the length of the bedroom?</h3>

From the given information, we get

Then $$\frac{(1/4)}{(9/4)} = \frac{1}{x}$

Solve this for x.

simplifying the value of x we get

Equate (1/9) to 1/x.

x = 9 (feet).

Convert 1.5 inches to feet using a proportion:

$$\frac{(1/4)}{(1.5)} = \frac{1}{y}$

Solve this for y.

simplifying the value of y we get

(1/4)y = 3/2

Multiply both sides of the equation by 4.

y = 6

Therefore, the length of the bedroom exists at x = 9 and y = 6.

pochemuha

Answer:

a)17.92

b) 16.83 .... 21.17

Step-by-step explanation:

ρ→ z

0.14 = -1.080319341

-1.080 = (x - 19)/1 = 17.92

~~~~~~~~~~~~~~~~~~

3% / 2 = 1.5%

1.5% - 98.5%

ρ→ z

0.015 = -2.170090378 .... -2.17 = (x-19) =16.83

0.985 = 2.170090378 .... 2.17 = (x-19) =21.17
