What is the measure of an angle whose sine is√3/2 ? 60 45 30
dem82 [27]
ANSWER

The required angle is
60 \degree

EXPLANATION

Let the angle whose sine is
\frac{ \sqrt{3} }{2}
be
x \degree

Then

\sin(x \degree)  =  \frac{ \sqrt{3} }{2}


We take the inverse sign of both sides to obtain,

x =  \sin ^{ - 1} ( \frac{ \sqrt{3} }{2} )

We use our scientific calculator to evaluate and obtain,

x = 60 \degree

Answer:

The new volume is 14,850cm³

Step-by-step explanation:

Given

Volume of a rectangular prism = 550cm

Required

Value of volume when the dimensions are tripled.

The volume of a rectangular prism is calculated using the following formula.

V = lbh

<em>When Volume = 550, the formula is written as follows</em>

550 = lbh

<em>Rearrange</em>

lbh = 550

However, when each dimension is tripled.

This means that,

new length = 3 * old length

new breadth = 3 * old breadth

new height = 3 * old height

<em>Let L, B and H represent the new length, new breadth and new height respectively</em>

In other words,

L = 3l

B = 3b

H = 3h

Calculating new volume

New volume = LBH

Substitute, 3l for L, 3b for B and 3h for H;

V = 3l * 3b * 3h

V = 3 * l * 3 * b * 3 * h

V = 3 * 3 * 3 * l*b*h

V = 27 * lbh

Recall that lbh = 550

So,

V = 27 * 550

V = 14,850

Hence, the new volume is 14,850cm³
