In circle S, angle QTR is an inscribed angle.<br><br><br> What is the measure of angle QRS?
docker41 [41]
<h2>Answer:</h2>

angle QRS = 51°

<h2>Step-by-step explanation:</h2>

The diagram for the question has been attached to this response.

From the diagram, some circle theorems can be applied.

<em><u>Circle theorem:</u></em>

The angle subtended by an arc of a circle at the centre is twice the angle subtended by it at any other point on the remaining part of the circle.

From the diagram, QR is the arc and therefore:

∠QSR = 2 x ∠ QTR

<em>Since ∠QTR = 39°</em>

=> ∠QSR = 2 x 39°

=> ∠QSR = 78°

<u><em>Other theorem:</em></u>

(i)The base angles of an isosceles triangle are equal.

Triangle QSR is an isosceles triangle, therefore, angles SQR and QRS are equal. i.e

∠SQR = ∠QRS

(ii) The sum of angles of a triangle is 180°. i.e

∠SQR + ∠QRS + ∠QSR = 180°

<em>Since ∠SQR = ∠QRS and ∠QSR = 78°</em>

=> ∠QRS + ∠QRS + 78° = 180°

=> 2(∠QRS) = 180° - 78°

=> 2(∠QRS) = 102°

<em>Divide both sides by 2</em>

=> ∠QRS = 51°

Therefore, angle QRS = 51°

Joe is playing a game with a regular die. If the number that turns up is even, he will gain 5 times the number that comes up. If
AleksandrR [38]

Answer:

30 dollars

Step-by-step explanation:

The question states that if an even number comes up then Joe will win 5 times of the number that shows up for example, if 2 comes up he will win 5×2 dollars i.e., 10 dollars. If an odd number shows up he will lose 10 times the number which i.e. if 1 shows up he will lose 1×10 = 10 dollars

It says in the question that Joe tosses a 3 which is an odd number so he will lose 10 times of 3

So he will lose 10×3 = 30 dollars.

Given sin θ = 7/25, find the value of a and b in the following statements.
Sergeu [11.5K]

Answer:

a = 7, b = 24 if quadrant 1

a = -7, b = -24 if quadrant 2

Step-by-step explanation:

Tan theta = sin(theta) × sec(theta)

a/24 = (7/25) × (25/b)

ab = 168

a = 168/b

1 + tan²(theta) = sec²(theta)

1 + a²/576 = 625/b²

1 + 168²/576b² = 625/b²

1 = 576/b²

b = 24 (+ or -)

a = 168/24 = 7 (+ or -)

2(x-5)+8=4<br><br>what does x equal?​
Ostrovityanka [42]

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(x−5)+8=4

(2)(x)+(2)(−5)+8=4(Distribute)

2x+−10+8=4

(2x)+(−10+8)=4(Combine Like Terms)

2x+−2=4

2x−2=4

Step 2: Add 2 to both sides.

2x−2+2=4+2

2x=6

Step 3: Divide both sides by 2.

2x/2 = 6/2

x=3
