A triangle has a base of 7m and an area of 17.5 squared. What is the height?

1 answer:

4 0

<span>Area of triangle = 1/2 x base x height17.5 = 1/2 x 7 x height17.5 = 3.5 x
</span>
<span>height = 17.5 /3.5 = 5 meters</span>

Which of following is equivalent to 1/x/x+3

LenaWriter [7]

The equivalent expression of the expression given as 1/x/x+3 is 1/x(x+3)

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

1/x/x+3

Rewrite as:

1/x/x+3 = (1/x)/x+3

Express the quotient as product

1/x/x+3 = 1/x * 1/x+3

Evaluate the product

1/x/x+3 = 1/x(x+3)

Hence, the equivalent expression of the expression given as 1/x/x+3 is 1/x(x+3)

If the sine ratio is given, then how can sin 0/2 be determined?

pogonyaev

Step-by-step explanation:

If you know, the sine. You must find the cos ratio, using the Pythagorean trig theorem.

Next, you use the half angle identity for sin

$\sin( \frac{ \alpha }{2} ) = \sqrt{ \frac{1 - \cos(a) }{2} }$

Example.

$\sin( \alpha ) = \frac{ \sqrt{3} }{2}$

We must find

$\sin( \frac{ \alpha }{2} )$

First, use the Pythagorean identity

$\sin {}^{2} ( \alpha ) + \cos {}^{2} ( \alpha ) = 1$

$( \frac{ \sqrt{3} }{2} ) {}^{2} + \cos {}^{2} (a) = 1$

$\frac{3}{4} + \cos {}^{2} (a) = 1$

$\cos {}^{2} (a) = \frac{1}{4}$

$\cos( \alpha ) = \frac{1}{2}$

Now use the half angle identiy

$\sin( \frac{ \alpha }{2} ) = \sqrt{ \frac{1 - \cos( \alpha ) }{2} }$

$= \frac{ \sqrt{1 - \frac{1}{2} } }{ \sqrt{2} }$

$= \frac{ \sqrt{ \frac{1}{2} } }{ \sqrt{2} }$

$= \frac{ \sqrt{ \frac{1}{2} } }{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{ \sqrt{1} }{ \sqrt{4} } = \frac{1}{2}$

So the answer for our example is 1/2
