Answer: a=101 b=79 c=83 d=97

Step-by-step explanation:

A: angles on a straight line add up to 180° so you would take away 79° from 180° which is 101°.

B: angles on a parallel lines are always the same, you can see that 79 is at the same position as b.

C: opposite angles are always the same so it would still be 83°.

D: d is on other side as c and this would add up to 180° so as we already know that c is 83° you would have to take away 83° from 180° to get d.

43x+2 = 64 + 455 - 766
Rudik [331]

43x+2=64+455−766

Step 1: Simplify both sides of the equation.

43x+2=64+455−766

43x+2=64+455+−766

43x+2=(64+455+−766)(Combine Like Terms)

43x+2=−247

43x+2=−247

Step 2: Subtract 2 from both sides.

43x+2−2=−247−2

43x=−249

Step 3: Divide both sides by 43.

43x /43  =  −249 /43

x =  −249 /43

Answer:

x =  −249 /43

Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination
  • Solving systems of equations by graphing

Step-by-step explanation:

<u>Step 1: Define Systems</u>

16x + 14y = 8

-63x - 14y = 133

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine 2 equations:                    -47x = 141
  2. Divide -47 on both sides:               x = -3

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define original equation:                    16x + 14y = 8
  2. Substitute in <em>x</em>:                                     16(-3) + 14y = 8
  3. Evaluate multiplication:                       -48 + 14y = 8
  4. Add 48 on both sides:                        14y = 56
  5. Divide 14 on both sides:                      y = 4

<u>Step 4: Graph Systems</u>

<em>Check the solution set.</em>

A 7-foot ladder is leaned against a building in such a way that the bottom of the ladder is 4 feet from the base of the wall. Fi
sladkih [1.3K]

The ground, the building, and the ladder form a right triangle, in which
the leaning ladder is the hypotenuse.

For the angle between the ladder and the ground, the 4-ft along the ground
is the side adjacent to the angle, and the 7-ft ladder is the hypotenuse.

         (adjacent side) / (hypotenuse) = cosine of the angle.

                                         Cosine(a) = 4/7 = 0.57143... (rounded)

                                                    Angle 'a' = <em>55.15 degrees</em> (rounded)
