Now I am not sure what length you're supposed to find for problem 9, but x = 3.3 i think.

10.)

(14+x)+(x+21) = 13

2x+35=13

2x = -22

x = -11

FE = -11 + 14 = 3 units

11.)

10 + 2x - 10 = 3x - 8

2x = 3x - 8

-x = -8

x = 8

10 + 2(8) -10 = 16 units

Need help with this
Marrrta [24]

Answer:

law of cosines states c^2=a^2+b^2-2abc

b^2=26^2+24^2-2(26×24)cos 134°

b^2=676+576-1248cos134°

cos134= -0.6946

b^2=1252-12(-0.6946)

12×(-0.6946)= -8.3352

b^2=1252-(-8.3352)

b^2=1252+8.3352

b^2=1260.33

b=√1260.33

b=35.50
