Answer:

B) No, supplementary angles are either of two angles whose sum is 180 degrees.

C) Yes, the triangles are congruent because the triangles have exactly the same size and shape

Step-by-step explanation:

B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.

C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.

Answer:

<em>She is incorrect.</em>

Step-by-step explanation:

<em>ABCD is a quadrilateral. Angle C measures less than 180 degrees. The sum of the measures of two supplementary angles equals 180 degrees. The sum of the measures of angles DCA and BCA equals the measure of angle C, but angle C measures less than 180 degrees, so the angles are not supplementary.</em>

X=15

1:25-10=X X=15

2:12+X=24 X=12

3:X>=10.5

4:59<4X X>14.75

5: 15

SO JUST 1 AND 5 ARE X=15

What is the difference? Complete the equation. -1 2/5 - (-4/5) = ?

AfilCa [17]

Answer:

First convert them which will be

-7/5 - (-4/5)

so when you subtract a negative number from negative number they actually subtract ex = -4-(-2) = -2

so its simply 7/5-4/5 then add a negative sign

so

3/5

now add negative sign so

-3/5

kirill [66]

Answer:

The number is 39

Step-by-step explanation:

Let the unknown number be <em>x</em>:

$(x-(-15))=2(x-24)\\x+15=2x-24\\39=x\\\therefore x=39$

A line has a slope of - 4 and includes the points (6,v) and (3,3). What is the value of v?

labwork [276]

Answer: v = - 9

Step-by-step explanation:

Since two points on the line are given, we use formula for slope.

Let (a,b) and (c,d) be two points on the line, the slope of the line is given by

m= $\frac{d-b}{c-a}$ .

Hence, using this we have

-4= $\frac{3-v}{3-6}$

Thus, we have

-4×(-3)=3-v⇒12=3-v⇒12-3=-v⇒v=-9
