Answer:

x = - 10 ± $\sqrt{y}$

Step-by-step explanation:

y = (x + 10)² , or

(x + 10)² = y ( take square root of both sides )

x + 10 = ± $\sqrt{y}$ ( subtract 10 from both sides )

x = - 10 ± $\sqrt{y}$

Y= (x+10)^2
Root both sides
±√y=x+10
-10
x= ±√y -10

Make b the subject<br>a=4b+2/3-b

Rasek [7]

Answer:

b = $\frac{3a-2}{9}$

Step-by-step explanation:

Given

a = 4b + $\frac{2}{3}$ - b, that is

a = 3b + $\frac{2}{3}$

Multiply through by 3 to clear the fraction

3a = 9b + 2 ( subtract 2 from both sides )

3a - 2 = 9b ( divide both sides by 9 )

$\frac{3a-2}{9}$ = b

a sailmaker is designing a mainsail for a newly constructed sailboat. the mainsail foot is 13 feet long, the luff is 10 feet lon

Vikentia [17]

(A) The mainsail foot is 13 feet long, the luff is 10 feet long, the leach is 6.93 feet long, and the mainsail area is 64.85 ft².
(B) The mainsail foot is 13 feet long, the luff is 10 feet long, and the luff forms a 50° angle with the leach at the head, requiring the length of the leach and the area of the mainsail.

<h3>What exactly is sines law?</h3>

The law of sines refers to the ratio of a triangle's side length to the sine of the opposite angle, which is the same for all sides.
SinA/a = SinB/b = SinC/c
Where A, B, and C represent the triangle's angle and a,b, and c represent the opposite sides of the triangle's angle.

So, Part A:

By employing the sines law,

SinA/10 = SinB/13
SinA/10 = Sin50/13
A = 36.10
C = 180-(180-36.10)
C = 93.90

So,

Sin36.10 / a = Sin50/ b = Sin93.90/c
Sin36.10 / 10 = Sin50/ 13 = Sin93.90/c
c = Sin93.90 × 13 ÷ Sin50
c = 16.93 ft

Now, Part B:

Area of the mainsail:

= 1/2 × abSinC
= 1/2 × 10 × 13 × Sin93.90
= 64.85

Therefore, the answers to both parts are:

(A) The mainsail foot is 13 feet long, the luff is 10 feet long, the leach is 6.93 feet long, and the mainsail area is 64.85 ft².
(B) The mainsail foot is 13 feet long, the luff is 10 feet long, and the luff forms a 50° angle with the leach at the head, requiring the length of the leach and the area of the mainsail.

The complete question is given below:

A sailmaker is designing a mainsail for a newly constructed sailboat. The mainsail foot is 13 feet long, the luff is 10 feet long, and the luff makes a 50° angle at the head with the leach.

Part A: Determine the length of the leach.

Part B: Find the area of the mainsail.
