Answer:

x = 19

Step-by-step explanation:

When two lines "cross" and intersect, it creates 2 pair of vertical angles.

The opposite angles are vertical angles and they are equal.

Given two angles (in expressions), they are vertical angles and hence are equal in measure. So we can write:

$6x-48=4x-10$

Now, we can use algebra and solve for x:

$6x-48=4x-10\\6x-4x=-10+48\\2x=38\\x=\frac{38}{2}\\x=19$

So,

x = 19

The largest doll is 12 inches tall. the height of each of the other dolls is 710710 the height of the next larger doll. write an

GrogVix [38]

the question doesn't say how many dolls. there would be an infinite number.
But we'll just form the equation for the nth doll.
Largest doll = 12 inches
2nd doll = (12) x 0.7
3rd doll = (12 x 0.7) x 0.7
4th doll = [(12 x 0.7) x 0.7) x 0.7

OK, We now see the pattern. Each successive doll is mult by the previous

doll height x 0.7
the Nth doll, 12 is mult by 0.7(n-1)
So, the height of the nth doll can be expressed as: 12 x 0.7(n-1)
example: 4th doll = 12 x 0.7(4-1) = 12 x 0.73
10th doll = 12 x 0.7(10-1) = 12 x 0.79 etc

If ∠ABE = 100° and ∠EDC = 100°, are the two triangles, ΔABE and ΔEDC similar? If so, by what criterion?

Arturiano [62]

Answer:

No, not possible to tell that the two triangles, ΔABE and ΔEDC are similar

Step-by-step explanation:

Similarity criterion:

1. AAA similarity : two triangles are similar if all three angles in the first

triangle equal the corresponding angle in the second triangle

2. AA similarity : If two angles of one triangle are equal to the corresponding angles of the other triangle, then the two triangles are similar.

3. SSS similarity : If the corresponding sides of the two triangles are

proportional, then the two triangles are similar.

4. SAS similarity : In two triangles, if two sets of corresponding sides

are proportional and the included angles are equal then the two

triangles are similar.

Now in the two triangles ABE and EDC :

∠ABE = 100°

∠EDC = 100°

∠ABE = ∠EDC

But only one congruent angle does not not prove that the two triangles are similar.

Hence, NOTHING CAN BE SAID ABOUT THE nature of the triangle.

Can any three side lengths make a triangle? Explain your reasoning.

Cerrena [4.2K]

In most cases its possible, but if the 2 of the shortest side lengths are added together and the sum is greater than the 3rd side length, than making a triangle is not possible.

When a car travels 100 km at a speed of 60km/h and returns back with a speed of 40km/h What will be average speed for whole jour

castortr0y [4]

The average speed of the whole journey of car based mentioned speeds is 48 km/hr.

The average speed is calculated by the formula -

average speed = total distance covered ÷ total time taken. The total distance covered is sum of distance of first and return journey. Total distance covered = 100 + 100

Performing addition

Total distance covered = 200 kilometres

Now total time taken = time taken on first journey + time taken for return journey

Total time taken = distance/speed + distance/return speed

Total time taken = 100/60 + 100/40

Performing division

Total time taken = 5/3 + 5/2

Total time taken = 10 + 15/6

Total time taken = 25/6 hour

Average speed = 200/(25/6)

Average speed = (200×6)/25

Performing division and multiplication

Average speed = 48 km/hr
