LAW OF SINES ANYONE?? need good explanation..ill give brainlest​

Mathematics
1 answer:
Dominik [7]2 years ago
3 0

Step-by-step explanation:

So i will try to explain it:

Scientists in the past invented this formula and theory of sines:

\frac{a}{ \sin(a) }  =  \frac{b}{ \sin(b) }  =  \frac{c}{ \sin(c) }

So the only thing is to put the given numbers into this formula :)

The task that i've just done is like this:

\frac{a}{ \sin(a) }

a is the numerator,that is delighted in the triangle,well its transparent.

What about denominator?

Here is the tip:

opposite to A- side angle-a has to be put into sin(a)

sin- how to calculate?

Easy just take the trigonometric functions formula or calculate in scientific calculator that's it.

\frac{a}{ \sin(a) }  =  \frac{b}{ \sin(b) }

one of this numbers might be unknown in that case solve by proportion(equation).

Carefully contemplate my answer in the media.

I hope you understood.

Good luck!

3.8*10 to the 9th power divided by 4*10 to the 2nd power
user100 [1]

Answer:

9.5\times 10^{6}

Step-by-step explanation:

1. Divide the coefficients and the exponentials separately

\dfrac{3.8 \times 10^{9}}{4 \times 10^{2}} = \dfrac{3.8}{4} \times \dfrac{10^{9}}{10^{2}}

2. Divide the coefficients

\dfrac{3.8}{4} = 0.95

3. Divide the exponentials

Subtract the exponent in the denominator from the exponent in the numerator.

\dfrac{10^{9}}{10^{2}} = 10^{(9 - 2)} = 10 ^{7}

4. Re-join the new coefficient and the new exponential

\dfrac{3.8 \times 10^{9}}{4 \times 10^{2}} = 0.95 \times 10^{7}

5. Put the new number into standard form

The number before the power of 10 must be greater than or equal to one and less than 10.

Multiply the answer by 10/10.

(0.95 \times 10^{7}) \times \dfrac{10}{10} = (0.95\times10) \times \dfrac{10^{7}}{10} = \mathbf{9.5\times 10^{6}}

Please help ill give brainiest answer!
eduard

1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.

58 + 58 + x = 180

116 + x = 180

x = 64

1. m{t}°=64 m{I}°=58

2. This one is easy because algebra is the key.

100 - x + 30 + 4x + 7x = 180

Add like-terms.

130 +10x = 180

10x = 50

\frac{50}{10}  = x = 5

x=5

The only thing that confuses me is the y. Is it 7xy, y as a side, or what? Feel free to reply
