Find the missing side or angle.

Nina [5.8K]

Answer:

$a=4.1$

Step-by-step explanation:

The Law of Cosines is given as:

$a^2=c^2+b^2-2cb\cos A$ .

Plugging in given values, we get:

$a^2=4^2+2^2-2\cdot 4 \cdot 2\cos 78^{\circ},\\a^2=16+4-16\cos 78^{\circ},\\a^2\approx \sqrt{16.673},\\a\approx \fbox{$4.1$}$ .

Evaluate the expression when a=-15 and b=-5 .<br><br> b+14 <br> ----------<br> 3

brilliants [131]

The answer is 3 because since b=-5 you get -5 and add it to 14 giving you 9 and then you divide 9/3 which gives you 3. Hope this helps :)

A worm travels 1250 millimeters.how many meters did the worm travel?

Trava [24]

we know that

$1\ meter=1,000\ millimeters$

by proportion

$\frac{1}{1,000}\frac{m}{mm} =\frac{x}{1,250}\frac{m}{mm} \\ \\1,000*x=1,250\\ \\x=1,250/1,000\\ \\x=1.25\ m$

therefore

the answer is

$1.25\ m$
