Law of cosines HELP MES

Lorico [155]

Answer:

70.52 degrees

Step-by-step explanation:

To find the angles, we must first find the lengths of each side of the triangle. Adding up the respective radii, we can see that

XY = 5+4 = 9 CM

XZ = 6+5 = 11 CM

ZY = 4+6 = 10 CM

Now we can apply the cosine rule

$C\:=\:\sqrt{A^2+B^2-2ABcosx}$

We need to rearrange the rule to solve for x, our missing angle

$x\:=\:cos^{-1}\left(\frac{a^2+b^2-c^2}{2ab}\right)$

solving for our unknown angle:

$x\:=\:cos^{-1}\left(\frac{9^2+10^2-11^2}{2\cdot 9\cdot 10}\right)$

$x\:=\:70.52^{\circ }$

Therefore angle YXZ is 70.52 degrees

2(2x - 4) = 4(x - 2) What is the solution

galben [10]

Answer: 0

Step-by-step explanation:

2(2x-4)=4(x-2) - Start off by diong distributive property on both sides

4x-8=4x-8 - Add 8 to both sides toget rid of it

4x=4x - Divide both sides by 4

0 = 0 - The 2 equations are equal therefore the answer is 0

Hope this helps!
