Answer:

angel A = 25°

angel B = 58°

Step-by-step explanation:

ACD + ACB = 180°

83° + ACB = 180°

ACB = 180° - 83°

ACB = 97°

ACB + angel B + angel A = 180°

97° + 4x + 1° + 9x + 4° = 180°

13x = 180° - 102°

13x = 78°

x = 78°/13

x = 6

angel A = 4x + 1°

angel A = 4(6) + 1°

angel A = 24 + 1°

angel A = 25°

angel B = 9x + 4°

angel B = 9(6) + 4°

angel B = 54 + 4°

angel B = 58°

Solve the following system using the SUBSTITUTION method. x - 3y = 2 2x - 6y = 6

notka56 [123]

ANSWER:

x – 3y = 2 ...(1)
2x – 6y = 6 ...(2)

On solving eq(1), we get

x – 2 = 3y
x – 2/3 = y

Plug the value of x in eq(2)

2x – 6(x - 2/3) = 6
2x – 2(x – 2) = 6
2x – 2x + 4 = 6
0 = 6 – 4
0 ≠ 2

So, given system of equations is not correct.
