<u>Answer:</u>

\sf x = 60^{\circ \:}

<u>given:</u>

  • adjacent side:  10
  • hypotenuse side: 20

<u>using cosine rule:</u>

\hookrightarrow \sf cos(x) = \dfrac{adjacent}{hypotense}

\hookrightarrow \sf \sf cos(x) = \dfrac{10}{20}

\hookrightarrow \sf \sf x = cos^{-1}(\dfrac{10}{20} )

\hookrightarrow \sf \sf x = 60^{\circ \:}

Determine the solution by using substitution. Write your answer as a point below (x,y).
sladkih [1.3K]

Answer:

(2,-2)

Step-by-step explanation:

To solve this using substitution you would take your second equation and plug it in for y of the first equation (4x-10= -3x+4). You then would add the 10 over (4x= -3+14). Next you add the 3x over(7x=14). Finally divide both sides by 7, which should give you x=2. Now all you have to do is plug the two in for x in one of your equations (which ever equation you prefer) (y=-3(2)+4). Solve the equation and you will then have the answer to y, which you can then put into a point.

#5- The ratio of the measurement of an angle to its supplement is : . Find the angle and its supplement
frutty [35]

This would be a great question, and fun to work on, if only you had actually
told us what the ratio of the angle to its supplement is. 

Sadly, the only part of the ratio that has survived the trauma of getting posted
is the colon in the middle. The numbers on each side of it have disappeared.
