The ratio of the same side interior angles of two parallel lines is 33:3. Find the measures of all eight angles formed by the pa
zheka24 [161]

9514 1404 393

Answer:

  all 4 acute angles: 15 degrees

  all 4 obtuse angles: 165 degrees

Step-by-step explanation:

The sum of same-side interior angles between parallel lines is 180°. The smallest of them will be 3/(33+3) = 1/12 of 180°, or 15°. The largest will be 180° -15° = (33/3)(15°) = 165°. All remaining angles are congruent to one or the other of these.

  All four acute angles are 15°; all four obtuse angles are 165°.

∠A and \angle B∠B are complementary angles. If m\angle A=(x+16)^{\circ}∠A=(x+16) ∘ and m\angle B=(x-12)^{\circ}∠B=(x−12) ∘ , the
Elena-2011 [213]

Answer:

Step-by-step explanation:

∠A + ∠B = 90    {∠A & ∠B are complementary}

x + 16 + x - 12 = 90

x + x + 16 - 12 = 90       {Combine like terms}

2x  + 4 = 90        { Subtract 4 form both sides}

        2x = 90 - 4

        2x = 86          {divide both sides by 2

        x   = 86/2

           x = 43

Michael's little brother plays with building blocks that are in the shape of a cube. Each cube has an edge length of 15 millimet
podryga [215]

Answer:

1350 mm²

Step-by-step explanation:

The area of each square face is the square of the edge length:

... face area = (15 mm)² = 225 mm²

There are 6 square faces on a cube, to the total surface area is 6 times that of one face:

... cube area = 6 × face area = 6×225 mm² = 1350 mm²

Solve the system of equations using substitution <br> 2x-3y=-1<br> X=y+1
Dima020 [189]

Substitute x = y + 1 into 2x - 3y = -1

2 - y = -1

Solve for y in 2 - y = -1

y = 3

Substitute y = 3 into x = y + 1

x = 4

Therefore,

<u>x = 4</u>

<u>y = 3</u>
