Answer:

236 cm^2

Step-by-step explanation:

Formula

Area = sector angle/360 * pi * r^2

Givens

Sector angle = 120

r = 15

Solution

Area = 120/360 * 3.14 * 15 * 15

Area = 1/3 * 3.14 * 225

Area = 235.5

Area = 236 cm^2

Westkost [7]

SOS:

Answer:

Take the square root of 36 and subtract 2.

Step-by-step explanation:

$x^2+4x=32\\(\frac{1}{2}*4=2; 2^2=4) : x^2+4x+4=36\\\sqrt{(x+2)^2}=\sqrt{36}\\ x+2=±6: -2+6=4, -2-6=-8$

Please help please and thank you

Katyanochek1 [597]

Step-by-step explanation:

$\text{We know:}\\\\\sin(-\alpha)=-\sin\alpha\\\\\sin(\alpha\pm k\cdot360^o)=\sin\alpha\\\\===============================\\\\\sin(360^o-\theta)=\sin\bigg(-(\theta-360^o)\bigg)=-\sin(\theta-360^o)=-\sin\theta$

What is the solution of the system? 7x+5y=19 and -7x-2y=-16 Need help ASAP

Stells [14]

Answer:

x = 2, y = 1

Step-by-step explanation:

7x + 5y = 19
-7x - 2y = -16

Use the elimination method to solve the system of equations. Add the terms from top to bottom. 7x and -7x cancel out.

0 + 3y = 3

Divide both sides by 3.

y = 1

Substitute 1 for y into the first equation.

7x + 5(1) = 19

7x + 5 = 19

Subtract 5 from both sides.

7x = 14

Divide both sides by 7.

x = 2
