In the diagram PQR and T are points on the circumference of a circle PTS and QRS are straight lines.PR is a diameter , QSP=28° a
Digiron [165]

Step-by-step explanation:

a)<PTR=90°(angles in a semicircle)

<RPT=50°

<PRT + <PTR + <RPT=180°(angles in a triangle)

<PRT=180-(90+50)

<PRT=40°

b)From ∆QTS

<TQS = <RTP =50°

<QTS=180-(50+28)

<QTS=102°

c)<QTR=180-(90+50)

<QTR=40°

How much 45” fabric is required to make a medium costume that includes Vest C and Pants C? vest 2 1/2 pants 2 7/8
marissa [1.9K]
Calculating amount of fabric

Fabric comes in many different widths, so unless you know beforehand exactly how wide the fabric you intend to buy is, you will need to do a little bit of figuring out in the store.

When you go to the store, take with you all the information you’ll need, like all the pattern piece measurements, the zip lengths, elastic lengths etc. Think about these things too, will you need lining and how much? Will you need iron-on interfacing to stiffen collars or use on facing? Do you need matching thread? Bring pens and paper too! If you have this information, I’m sure most fabric store assistants will be happy to help you figure out how much you will need to buy.

1. Find the value of
spin [16.1K]

9514 1404 393

Answer:

  1. -√5
  2. 3/5
  3. -4/5

Step-by-step explanation:

The relevant relations are ...

  sec = ±√(tan² +1)

  cos = 1/sec

  csc = 1/sin = ±1/√(1 -cos²)

Sine and Cosecant are positive in quadrants I and II. Cosine and Secant are positive in quadrants I and IV.

__

1. sec(θ) = -√((-2)² +1) = -√5

2. cos(θ) = 1/sec(θ) = 1/(5/3) = 3/5

3. csc(θ) = -1/√(1 -(-3/5)²) = -√(16/25) = -4/5

Idek why brainly deleted my last one but-<br><br><br>solve for x<br><br>2/3x - 4 1/2 = -8
BaLLatris [955]

Answer:

The answer is x= -5 1/4

Step-by-step explanation:

Let's solve your equation step-by-step.

2/3x−4 1/2=−8

Step 1: Simplify both sides of the equation.

2/3x+−9/2=−8

Step 2: Add 9/2 to both sides.

2/3x+−9/2+9/2=−8+9/2

2/3x=−7/2

Step 3: Multiply both sides by 3/2.

(3/2)*(2/3x)=(3/2)*(−7/2)

x=−21/4

Answer:

x= −5 1/4
