How are the triangles congruent? A) not congruent B) ASA C) SAS D) AAS

Answer:

1:Gavin is incorrect.

2:4

3: 1/4

4: 1/12

Step-by-step explanation:

Answer:

∠ A = 82°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

A is an exterior angle of the triangle, then

∠ A = 49° + 33° = 82°

162 because ya I did that question

Answer:

ΔGJH ≅ ΔEKF

HL: GH and EF

SAS: FK and JH (or GH and EF)

ASA: ∠JGH and ∠FEK (or ∠EFK and ∠JHG)

ΔGFJ ≅ ΔEKH

SSS: KH and FJ

SAS: ∠KEH and ∠FGJ

Step-by-step explanation:

List whatever angles/sides need to be congruent for the two triangles to be congruent.

Prove ΔGJH ≅ ΔEKF using....

- HL (Hypotenuse + Leg)

           We already have two legs that are congruent (EK and GJ), so we just need the hypotenuses (GH and EF) to be equal.

- SAS (Side + Angle + Side)

         1 pair of sides (EK and JG) are equal, and m∠EKF = m∠GJH. So we need one more side. You can either use FK and JH or GH and EF.

- ASA (Angle + Side + Angle)

         1 pair of angles (∠EKF and ∠GJH) are already given as equal, and 1 pair of sides (EK and GJ) are equal. We just need one more pair of angles. So either ∠JGH and ∠FEK or ∠EFK and ∠JHG.

Prove ΔGFJ ≅ ΔEKH using...

- SSS (Side + Side + Side)

          Two pairs of sides (EK + GJ and EH + FG) are equal, so KH and FJ need to be equal.

- SAS (Side + Angle + Side)

          FG + EH and KE + GJ are equal. We need to use the angle in between them to use SAS, so ∠KEH and ∠FGJ need to be equal.

Answer:

258.75

Step-by-step explanation:

5x5=25

25x4.5=112.5

112.5x2.3=258.75

Answer:

Step-by-step explanation:

Formula

Area = 1/2 (b1 + b2)*h

Givens

b1 = 5

b2 = 11.5

h = 4.5

Solution

Area = 1/2 (5 + 11.5)* 4.5

Area = 1/2 (16.5)*4.5

Area = 1/2 (74.25)

Area = 37.125

Answer:

200 questions

Step-by-step explanation:

If he missed 68 questions and got a 66%, that means 68 is 34% of the total number of questions

To find the total questions, divide 68 by 0.34

68/0.34

= 200

So, there were 200 total questions on the final exam

9

Step-by-step explanation:

4-1=3

3u--> 27

1u--> 9

Answer:

This can be solved like this:

4x-3x+9=20

Solving 4x-3x

x+9=20

Transposing +9

x=20-9

And now we have, x=11

Answer:

x=11

Step-by-step explanation:

first solve the things you can simplify on one side of the equation:

4x-3x+9=20--->x+9=20

then, get the variables onto one side of the equation and numbers unto the other.

*minus 9 from each side*

x=11

Answer:

Perimeter of A = 46cm

Area of A = 112cm^2

Perimeter of B = 61cm

Area of B = 118cm^2

Step-by-step explanation:

So there are two shapes. I divided one into 2 parts ( shape A ) . And the other into three ( shape B

Shape A:

PERIMETER = S + S +S +S + S + S + S + S ( THE SHAPE HAS 8 SIDES )

= 5 + 5 + 20 + 11 + 3 + 3 + 5 + 4 ( THIS INCLUDES THE MISSING SIDES )

= 46 CM

AREA- To find the area you divide the shape

Part 1 - 4* 3 = 12cm^2 Part 2 - 20 * 5 = 100cm^2

Final part ( add part a and b ) - 12 + 100 = 112cm^2

Shape B:

PERIMETER = S + S + S + S + S ..,........ (UNTIL YOU GET TO 12 SIDES PROVIDED THE SHAPE HAS 12 SIDES :) )

= 12 + 2 + 2 + 4 + 5 + 4 + 4 + 4 + 6 + 6 + 12 + 5

= 61 CM

AREA- To find the area you divide the shape

Part 1 - 12* 2 = 24cm^2 Part 2 - 4 * 3 = 12cm^2 Part 3 - 12 * 6 = 72 cm ^2

Final part ( add part a, b and c ) - 12 + 72 + 24 = 108cm^2

Answer:

5 5/8 miles per hour

Step-by-step explanation:

Martin can run 3 ¾ miles in 2/3 of an hour. Write a unit rate to describe the situation and explain the context.

We are asked to write the unit rate , this means we are to find out how many miles he can run per hour

Hence,

2/3 hour = 3 3/4 miles

1 hour = x

Cross Multiply

2/3 hour × x = 3 3/4 miles × 1 hour

x = 3 3/4 miles × 1 hour/ 2/3 hour

x = 3 3/4 ÷ 2/3

x = 15/4 ÷ 2/3

x = 15/4 × 3/2

x = 45/8

x = 5 5/8 miles per hour

x=5,11

y=8,8,11

Answer:

y = 10x

Step-by-step explanation:

When x = 2, y = 20

When x = 5, y = 50

When x = 7, y = 70

In each of these examples, y = 10 * x.

The answer is y = 10x.

Answer:

Step-by-step explanation:

Given the expression

-x^2 + x + 3 x - 3

Factorize

(-x^2 + x) + (3 x - 3)

-x(x-1)+3(x-1)

= (x-1)(-x+3)

Hence one of the quotient is -x+3

Answer:

The all-time medal table for all Olympic Games from 1896 to 2018, including Summer Olympic Games, Winter Olympic Games, and a combined total of both, is tabulated below. These Olympic medal counts do not include the 1906 Intercalated Games which are no longer recognized by the International Olympic Committee (IOC) as official Games. The IOC itself does not publish all-time tables, and publishes unofficial tables only per single Games. This table was thus compiled by adding up single entries from the IOC database.[1]

The results are attributed to the IOC country code as currently displayed by the IOC database. Usually, a single code corresponds to a single National Olympic Committee (NOC). When different codes are displayed for different years, medal counts are combined in the case of a simple change of IOC code (such as from HOL to NED for the Netherlands) or simple change of country name (such as from Ceylon to Sri Lanka). As the medals are attributed to each NOC, not all totals include medals won by athletes from that country for another NOC, such as before independence of that country. Names in italic are national entities that no longer exist. The totals of NOCs are not combined with those of their predecessors and successors.

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Answer:

This question has a slope of zero.

Step-by-step explanation:

When trying to solve a problem like this, what I recommend doing is subtracting the y value in the first ordered pair from the y value in the second ordered pair, and doing the same for the x values. To write it as a formula,

y2 - y1

––––– = m          the 2 in the formula means that the y or x value was from the  

x2 - x1                  second ordered pair. The 1 means it was from the first                                      

                            ordered pair. The m means slope.
