Answer:

D would be the correct answer

Step-by-step explanation:

You really have to know the names of each set of congruent angles and it results to a process of elimination. A is wrong because even though they are congruent, they are identified as vertical angels. B is wrong because once again they are congruent yes, but their correct name is alternate exterior angles. C is wrong because well, they are not even congruent. that means D is all that is left and yes the set is both congruent and corresponding.

Find the distance between the following points: (0,0,0) and (-2,6,3)

Answer:

3. 7

Step-by-step explanation:

The distance formula applies in 3 dimensions as well as 2.

d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)

d = √((-2)² +6² +3²) = √(4 +36 +9) = √49

d = 7

The distance between the two points is 7 units.

The circumference of a circle can be found using the formula C = 2r. Which is an equivalent equation solved for r? r = C r = C(2

vaieri [72.5K]

Answer:

r equals StartFraction C Over 2 pi EndFraction

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

where

r is the radius of the circle

Solve for r

That means -----> isolate the variable r

Divide by 2π both sides

$\frac{C}{2\pi}=\frac{2\pi r}{2\pi}$

Simplify right side

$\frac{C}{2\pi}=r$

Rewrite

$r=\frac{C}{2\pi}$

so

r equals StartFraction C Over 2 pi EndFraction

Sum of the ages of a father and the son is 40 years. If father's age is 3 times that of his son, then father's age is ________ *

nikklg [1K]

Answer:

30

Step-by-step explanation:

Sum of ages= 40

Let the sons age be x

Fathers age = 3 times x or ,3x

So 3x+x=40

4x= 40

x= 40/4

= 10

Therefore the fathers age = 3x

= 3*10

= 30
