7(5a-4) - 1 = 14 - 8a. Start off by multiplying 7by (5a-4).

35a - 28 - 1 = 14 - 8a. Combine like terms.

35a - 29 = 14 - 8a. Add 8a to each side and add 29 to each side.

43a = 43. Divide each side by 43.

a = 1

Answer:

a=1

Step-by-step explanation:

7(5a-4)-1=14-8a

Distribute

35a - 28 -1 = 14 -8a

Combine like terms

35a -29 = 14 -8a

Add 8a to each side

35a+8a -29 = 14 -8a+8a

43a -29 = 14

Add 29 to each side

43a -29+29 = 14+29

43a = 43

Divide each side by 43

43a/43 = 43/43

a =1

Find the measure , I need help
ehidna [41]

Answer:

166°

Step-by-step explanation:

Since ∠A = ∠B,

the equation below helps to find the value of x and angle A:

  • 7x + 40° = 3x + 112°
  • 7x - 3x = 112° - 40°
  • 4x = 72°
  • x = 72°/4
  • x = 18°
  • ∠A = 7*18° + 40° = 166°
