Answer:

√2

Step-by-step explanation:

Angle ( θ ) = 45

Hypotenuse side = 2

Opposite side = x

Formula : -

sin θ = Opposite side / Hypotenuse side

Note :

The value of sin 45 = 1/√2

sin 45 = x/2

1/√2 = x/2

Cross multiply,

x*√2 = 2*1

x√2 = 2

2 can be simplified as √2 * √2

x√2 = √2*√2

Divide √2 on both sides,

x = √2

solve systems of equation. equation number 1: 9 x squared + 4 y squared equals 144. equation 2: x squared plus y squared equals
grigory [225]
9x^{2} + 4y^{2} =144
x^{2} + y^{2}=24

9x^{2} + 4y^{2} =144
 4x^{2} + 4y^{2}=96
by the difference 
5x^{2}=48
so x=\sqrt{\frac{48}{5}} or x=-\sqrt{\frac{48}{5}}
and y^{2}=24-\frac{48}{5}
then y=\sqrt{\frac{72}{5}} or -\sqrt{\frac{48}{5}}

What is the answer? Please help. Urgent.

Given:

A figure that contains a right triangular prism and cuboid.

To find:

The volume of the figure.

Solution:

The dimensions of cuboid are 16 in, 7 in and 3 in.

So, the volume of the cuboid is:

V_1=Length\times Width \times height

V_1=16\times 7 \times 3

V_1=336

The base of the prism is a right angle with base 3 in and height 5 in, and the length of the prism is 6 in. So, the base are of the prism is

B=\dfrac{1}{2}\times Base\times Height

B=\dfrac{1}{2}\times 3\times 5

B=7.5

The volume of a prism is:

V_2=Bh

Where, B is the base area and h is the height of the prism.

V_2=(7.5)(6)

V_2=45

The volume of combined figure is:

V=V_1+V_2

V=336+45

V=381

Therefore, the volume of the figure is 381 cubic in.
