The four-sided geometric figure pictured is called a parallelogram. One feature of parallelograms is that opposite sides have eq

ual lengths. The dotted line splits the parallelogram into two triangles. What is true about the congruency of the two triangles? 1)More information is needed. 2)The triangles can be proven congruent using SSS. 3)The triangles can be proven congruent using HL. 4)The triangles are not congruent.

Answer:

The answer is the option 2

The triangles can be proven congruent using SSS

Step-by-step explanation:

we know that

The property of a parallelogram are the following

a) Opposite angles are congruent

m

b) Consecutive angles are supplementary

m

c) The diagonals of a parallelogram bisect each other

d) Opposite sides are parallel and congruent

AD=BC, AB=DC

see the attached figure to better understand the problem

Remember that

If two triangles are congruent by SSS

then

their corresponding sides are congruent

In this problem

the triangles ABD and CDB are similar by SSS

because

AD=BC, AB=DC -----> Opposite sides are congruent

12(3w+8)=25
36w+96=25 ( I used the distributive property)
          -96 . -96
36w=-71
w=-1.972222.... ( I divided both sides by 36)

Can someone please help me with this :(

Answer:

first find the surface area of one of the square and one of the triangle.

then multiple it by the number of square and triangle they have

finally add the total surface area of the triangle with the total surface area of the square.

Step-by-step explanation:

  1. for one square

area= base * width

= 10*10

=100

total area of square= number of square * area of one square

t=6*100

t=600

  • for one triangle

area = 1/2 base * height

= 1/2 *10*8.66

=43.3

total area of triangle=number of triangle* area of one triangle

t2=8*43.3

=346.4

total surface area= total surface area of the square+ total surface area of the triangle

=600+346.4

=946.4 in^2

Im confused, can someone help?
Bumek [7]
Well, the y-intercept is represented by B. So b would be the dot crossing the y-axis in each graph (which you already circled). Next, the slope for top left is: -1.5, top right is: -1.7, bottom left is: 3, and bottom right is: 1.33. I got those by using this very helpful website named Desmos. Now, I’m order to write the equation for each graph is very simple, all you have to do is put in the slope and y-intercept into the equation. For example, the top left one would be:
y = -1.5x + 4 since we know that the slope is equal to -1.5 and the y-intercept is equal to 4. Hope this helps :)
