∠A=5x−18. ∠B=3x+42∘ solve for x and then find the measure of ∠A
KatRina [158]

Answer:

x = 30 ∠A = 132 degrees

Step-by-step explanation:

Set the equations equal to each other to solve for x

5x - 18 = 3x + 42

-3x        - 3x               Subtract 3x from both sides

2x - 18 = 42

    + 18  + 18              Add 18 to both sides

2x = 60                     Divide both sides by 2

x = 30

Now plug this into the equation for angle A

∠A = 5(30) − 18        Multiply

∠A = 150 - 18           Subtract

∠A = 132 degrees

An ancient Sicilian legend says that the barber in a remote town who can be reached only by traveling a dangerous mountain road
faust18 [17]

Answer:

No there cannot be.

Step-by-step explanation:

In explaining this question, I would like us to take into account who the barber is,

" the barber is the one who shaves all those, and those only, who do not shave themselves".

This barber cannot be in existence because who would shave him? If he should shave himself then there is a violation of the rule which says he shaves only those who do not shave themselves. If he shaves himself then he ceases to be a barber. And if he does not shave himself then he happens to be under those who must be shaved by the barber, because of what the rule says. But then he is the barber.

This lead us to a contradiction.

Neither is possible so there is no such barber.

What is the distance from the point (−3, −b, c) to the origin?
lord [1]

Answer:

  \sqrt{9+b^2+c^2}\,\text{units}

Step-by-step explanation:

The distance formula tells you the distance d between the points (0, 0, 0) and (-3, -b, c) is ...

  d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²) = √((-3-0)² +(-b-0)² +(c-0)²)

  = √(9 +b² +c²)
