The given :right angled triangle
:there are two equal sides
solution
1 if triangle name is ABC
then AB=AC
then triangle ABC is a isosceles triangle
then angle BAC =angle CBA =2X
and any triangle in life there angles sum =180
2x + 90 = 180
2x=180-90
2x=90
x =  \frac{90}{2}
x=45

Andre45 [30]

Answer:

The Null hypothesis is a claim the researcher is trying to disprove. (I think)

Step-by-step explanation:

The null hypothesis states that there is no relationship between the two variables being studied (one variable does not affect the other). It states results are due to chance and are not significant in terms of supporting the idea being investigated.

If the Zeros are 2 and 8 what's the axis of symmetry?
lions [1.4K]

Answer:

Step-by-step explanation:

x=2,x-2=0

x=8

x-8=0

y=(x-2)(x-8)=x²-2x-8x+16=x²-10x+16

=x²-10x+25-25+16

=x²-10x+25-9

y=(x-5)²+9

axis of symmetry is x-5=0 or x=5

Use point slope form to write the lines with the given slope and point in slope intercept form.m= -1(-5,-4)
lara31 [8.8K]

The slope point form is

y-y1=m(x-x1)

m is the slope

x1, y1 are the coordinates of a point on the line

The slope of the line is -1

m = -1

point (-5, -4) lies on the line

x1 = -5 and y1 = -4

Let us substitute them in the form above

y-(-4)=-1(x-\lbrack-5\rbrack)

Remember (-)(-) = (+)

y+4=-1(x+5)

The equation of the line in the slope-point form is y + 4 = -1(x + 5)
