Mathematics
1 answer:
zloy xaker [14]3 years ago

Answer:

y = 8

x = 21

Step-by-step explanation:

Find x first. Since there is a straight line, we can conclude it's equal to 180 degrees.

11x + 10 -61 = 180

Add 10 to negative 61.

11x - 51 = 180

Add 51 to both sides.

11x = 231

Divide 11 both sides

x = 21.

Now put x in the equations to solve.

This is for the small angle on the right side.

(21+10) = 31

This is for the big angle on the right side.

(10(21) - 61)

210 - 61 = 149.

Now for the other side, we know the degree for the smaller side on the left side since it's a vertical angle.

31 degrees for top left angle. Since we know this side is 180 just subtract 31 from 180 and you'll get 149.

18y + 5 = 149

Subtract 5 both sides.

18y = 144

y = 8.

What is (128 +7x- 12) = (4x - 3)?​
podryga [215]

Answer:

x = -119/3 = -39 2/3

Step-by-step explanation:

(128 +7x- 12) = (4x - 3)

Combine like terms

(116 +7x) = (4x - 3)

Subtract 4x from each side

116 +7x-4x=4x-4x-3

116 +3x = -3

Subtract 116 from each side

116-116 +3x = -3-116

3x = -119

Divide each side by 3

3x/3 = -119/3

x = -119/3

x = -39  2/3

I really need help. Someone please help me with this.
9966 [12]

Answer:

  angles 1, 3, 6, 8 = 142°

  angles 2, 4, 5, 7 = 38°

Step-by-step explanation:

Vertical angles and corresponding angles are congruent, as are alternate interior angles. Hence the angles 1, 3, 6, 8 are all congruent:

  ∠1 = ∠3 = ∠6 = ∠8 = 142°

Each of the remaining angles forms a linear pair with one or another of those, so is its supplement:

  ∠2 = ∠4 = ∠5 = ∠7 = 180° -142° = 38°
