Answer:

y = 9.1

Step-by-step explanation:

By applying Sine rule in the given triangle WXY,

$\frac{\text{SinW}}{\text{XY}}=\frac{\text{SinY}}{\text{WX}}=\frac{\text{SinX}}{\text{WY}}$

$\frac{\text{SinW}}{\text{w}}=\frac{\text{SinY}}{\text{y}}=\frac{\text{SinX}}{\text{x}}$

Since m∠W + m∠X + m∠Y = 180°

m∠W + 58° + 106° = 180°

m∠W = 180° - 164°

m∠W = 16°

$\frac{\text{Sin16}}{\text{w}}=\frac{\text{Sin106}}{\text{y}}=\frac{\text{Sin58}}{\text{8}}$

$\frac{\text{Sin106}}{\text{y}}=\frac{\text{Sin58}}{\text{8}}$

y = $\frac{8\times (\text{Sin106})}{\text{SIn58}}$

y = 9.068

y ≈ 9.1

Make q the subject of the formula 2(q+p) = 1+5q. Give your answer in the form ap-b/c where a,b and c are all positive integers

musickatia [10]

Answer:

$\frac{2p-1}{3}$

Step-by-step explanation:

Since you want to get q only and q appears in both side of the equation. Try to isolate q to one side.

1) Expand 2(q+p)

2q + 2p = 1 + 5q

2) Move all q terms to one side

5q - 2q = 2p - 1

3q = 2p - 1

3) Divide 3 on both side (to isolate q)

q = $\frac{2p-1}{3}$

A printer designs a tag in the shape of a circle with a smaller circle cut out. She cuts her prototype from a 5 in. by a 7 in. i

Nonamiya [84]

The circumference of the larger circle is about 12.57 inches. The circumference of the smaller circle is about 3.14 inches. So, the total length of gold leaf on a tag is approximately 15.71 inches.

<h3>How to illustrate the circle?</h3>

The circumference will be:

= 2πr

= 2 × 3.14 × 2

= 12.57 inches.

The circumference of the smaller circle will be:

= 2πr

= 2 × 3.14 × 0.5

= 3.14

The total length will be:

= 12.57 + 3.14

= 15.71 inches.

Solve 11b^2-9=-68 using the square root method

Vladimir79 [104]

Answer:

b=i* $\sqrt{\frac{59}{11} }$ or -i* $\sqrt{\frac{59}{11} }$

Step-by-step explanation:

11b^2-9=-68

11b^2=-59

b^2=-59/11

b=i* $\sqrt{\frac{59}{11} }$ or -i* $\sqrt{\frac{59}{11} }$

"i" in this case is an imaginary number, equal to $\sqrt{-1\\}$
