Answer:

Using CPCTC, we know that congruent parts of the congruent triangles are congruent.

Given: ∆ABC ≅ ∆DEF

BC ≅ FE  ⇒ CPCTC. IF FE = 5 (Given), & FE ≅ BC (CPCTC) ∴ BC = 5 (Transitive Property of Equality.)

BA ≅ DE ⇒ CPCTC. IF DE = 11 (Given) & DE ≅ BA (CPCTC) ∴ BA = 11 (Transitive Property of Equality.)

m∠D ≅ m∠A ⇒ CPCTC. Congruent Parts of Congruent Triangles are Congruent. If ∆ABC ≅ ∆DEF (given), then through CPCTC, m∠D ≅ m∠A.

Answer:

BC = 5

BA11

angle D = 27

Step-by-step explanation:

If the triangles are similar

ABC ≅ DEF

That means AB ≅ DE

BC ≅ EF

and CA ≅ FD

We want to find AB  so it is equal to DE  

BC = EF = 5

BA = AB = DE =11

We also know  the angles are equal

A = D

B = E

C = F

Angle A = angle D = 27

A boat takes 4 hours to go 20 miles upstream. It can go 32 miles downstream in the same time. Find the rate of the current and t
KonstantinChe [14]
Let the boat speed in still water be b.
Let the current speed be c.
The speed going upstream is 20/4 = 5 mph.
The speed going downstream is 32/4 = 8 mph.
b - c = 5 ........(1)
b + c = 8 .......(2)
Adding equations (1) and (2) we get:
2b = 13
b = 13/2 = 6.5
Plugging in the value for b into equation (1) we find c = 1.5.
The boat speed in still water is 6.5 mph and the current speed is 1.5 mph.

What is the distance between the points (-2,4) and (6,-4), rounded to the nearest tenth
jarptica [38.1K]

9514 1404 393

Answer:

  11.3 units

Step-by-step explanation:

The distance can be found using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((6 -(-2))² +(-4-4)²) = √(8² +(-8)²) = √(64·2)

  d = 8√2 ≈ 11.3

The distance is approximately 11.3 units.

In a three hour TV broadcast the commercials show 29% of the time. How many minutes of commercials are shown each hour? Round to
Sedaia [141]

Answer:

There are 17.4 minutes of commercials are shown each hour.

Step-by-step explanation:

An hour has 60 minutes.

So in 3 hours, there are 3*60 = 180 minutes.

The commercials show 29% of the time.

So we have 0.29*180 = 52.2 minutes, in total, of commercial.

Per hour, we have 52.2/3 = 17.4 minutes of commercial.

I'll do number 11 for you 

Area of a sector can be found using 
A = (πr²)C/360  where C is the measure of your central angle
A =  \pi  (6^{2} )( \frac{75}{360} )
A ≈ 23.56 m²

Oh, I guess rounded to the nearest tenth is 23.6
