Answer:

b = 5

Step-by-step explanation:

4 ( 3b + 2 ) - 5b = 43 Given

( 4 • 3b + 4 • 2 ) - 5b = 43 Distributive Property

12b + 8 - 5b = 43

12b - 5b + 8 = 43 Combine like terms

7b + 8 = 43

7b + 8 - 8 = 43 - 8 Subtraction Property of Equality

7b = 35

7b / 7 = 35 / 7 Division Property of Equality

b = 5

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
