Answer:
Sorry, it's actually the third one, 4.8 feet
Step-by-step explanation:
First, you divide the length of the family room tv by the length of the tv in Louise's room
5 divided by 1.5 equals 3.33
Then, you divide the width of the family room tv to get the width of Louise's tv
3 divided by 3.33 is 0.9
Now, you follow the formula for perimeter.
(0.9 + 1.5) x 2 = 4.8
The perimeter of Louise's tv is 4.8 feet.
I found the value of x to be 6 by adding the two equations together and setting them equal to 180.
2x^2+3x-5+x^2+11x-7=180
When you solve for x you get x=6
Then you plug 6 in for x in each angle. The first angle is 85 and the second is 95.
I have not seen this before hopefully some can help u for the answer like this answer is
Answer:
Step-by-step explanation:
c^2=a^2+b^2-2abcosC
cosC= (a^2+b^2-c^2)/(2ab)
C=arccos[(a^2+b^2-c^2)/(2ab)]
C=arccos(90^2+55^2-50^2)/(2(90)55)
C=arccos(8625)/(9900)
C=29.4 degrees
