A rectangle is formed by placing 2 identical squares side by side. The area of the rectangle is 98 cm2. What is the perimeter of

kherson [118]

The rectangle area is 98. So if you split it in half, you would get 2 squares. Half of 98 is 49.

If it is now a square, you now simply know, that 7*7=49. Meaning that The sides of the square are 7 each.

7 times the 4 sides equals 28. So the perimeter of one square is 28.

Angle 0 is in the second quadrant, and sin 0=3/5

Aneli [31]

ANSWER

The value of theta in the second quadrant is,

$143.1 \degree$

EXPLANATION

The given trigonometric equation is
$\sin( \theta) = \frac{3}{5}$

This implies that,

$\theta= arcsin(\frac{3}{5} )$

This implies that the principal solution is
$\theta = 36.9 \degree$
and it is an angle in the first quadrant.

But the solution we are looking for is an angle in the second quadrant.

This is given by
$180 - \theta = 180 - 36.9 = 143.1 \degree$

2x + 3y = 26<br> 3x + 5y = 40

vaieri [72.5K]

2x + 3y = 26 -- equation 1

3x + 5y =40 -- equation 2

(Equation 1) * 3

6x + 9y = 78 -- equation 3

(Equation 2) * 2

6x + 10y = 80 -- equation 4

(Equation 4) - (Equation 3)

y = 2 -- equation 5

(Equation 5)'s value of y into (Equation 1)

2x + 3(2) = 26

2x = 20

x = 10

Thus x = 10 and y = 2

Hope that helps!
