irakobra [83]

you will need to use the law of cosines since this picture does not indicate that this is a right triangle

c^2 = a^2 + b^2 – 2ab cos C,

16^2 = 17^2+8^2 -2*17*8*cosC

256=289-272cosC

-33=-272cosC

33/272 = cosC

cos^-1 (33/272)=C  taking the inverse cos

C=83.0  (to the nearest tenth)

b^2 = a^2 + c^2 – 2ac cos B,

8^2 = 17^2 +16^2 -2*17*16cosB

64=289-544cosB

-225=-544cosB

225/544=cosB

cos^(-1) =B

B=65.5

A=180-83-65.6

A=31.4

-2(y+12)=y-9
lions [1.4K]

1) y= -5

2) m = -1

3) k = 3

4) y = -5

Step-by-step explanation:

1) -2(y+12)=y-9

Solving:

-2(y+12)=y-9\\-2y-24=y-9\\Combining\,\,like\,\,terms:\\-2y-y=-9+24\\-3y=15\\y=15/-3\\y=-5

2) 8(-1+m)+3 = 2 [m-5 1/2]\\

Solving:

8(-1+m)+3 = 2 [m-5 \frac{1}{2} ]\\-8+8m+3=2 [m-\frac{11}{2} ]\\8m-5=2 [\frac{2m-11}{2} ]\\8m-5=2m-11\\Combining\,\,like\,\,terms:\\8m-2m=-11+5\\6m=-6\\m=-6/6\\m=-1

3) 8(12-k)=3(k+21) (Note: Considering 8(12-k)=3(k+21) instead of 8(12-k)=3(k=k+21))

Solving:

8(12-k)=3(k+21)\\96-8k=3k+63\\Combining\,\,like\,\,terms:\\-8k-3k=63-96\\-11k= -33\\k=-33/-11\\k=3

4) 2y-3(2y-3)+2=31

Solving:

2y-3(2y-3)+2=31\\2y-6y+9+2=31\\Combining\,\,like\,\,terms:\\2y-6y=31-9-2\\-4y=20\\y= 20/-4\\y = -5
