How many congruent sides does a SAS, ASA, AAS, and HL triangle each have ?
irga5000 [103]
Check the picture below.

notice that, through to meet all those tests, the triangles need to only have two sides that are congruent all the while.

keeping in mind is a right-triangle, because the HL test only applies to right-triangles.

write the standard form of the equation of the line through the given point with the given slope THROUGH:(1,2), slope =7, 50 POI
yan [13]
A standard equation for a line is usually written as y=mx+b, m being the slope and b the y-intercept. We already have the slope, 7. To find the y-intercept we need to make an equation. The coordinates (1,2) will help us. We can plug the x from our point into the equation as well as our y. 1 is the x and 2 is the y. Therefore our equation is 2=7(1)+b. Now we solve. 7×1=7, so 2=7+b. Then we subtract 7 from both sides to get rid of the 7 on the right side. In addition, the 7 is positive so subtracting will get rid of it.
2=7+b
-7 -7
2-7 is -5. Therefore -5 is b.
Now we can make an equation.
y will remain y.
x will remain x.
m = 7
b = -5
y=7x+(-5) or y=7x-5

I hope this helped! (:

How many tenths are there in four fifths?
sleet_krkn [62]

So to find how many tenths, or 1/10's, there are in four fifths, or 4/5, divide 4/5 by 1/10.

\frac{4}{5} \div \frac{1}{10}

Now, remember that <u>dividing by a number is equivalent to multiplying by its reciprocal</u>. To find the reciprocal, just flip the numerator and denominator around. In this case, 1/10 would become 10/1. Flip 1/10 to its reciprocal, change the sign to multiplication, and multiply numerators with numerators and denominators with denominators:

\frac{4}{5}\times \frac{10}{1}=\frac{40}{5}=8

<u>In short, there are 8 tenths in four fifths.</u>

Solve x^2 - 4x - 7 = 0 by completing the square. What are the solutions?
sergejj [24]

Answer:

x = ±√11 +2

Step-by-step explanation:

Given in the question an equation,

x²- 4x - 7 = 0

Step 1

take 7 to the right side of equation

x²- 4x = 7

Step 2

To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of b, the coefficient of x

2ab = -4x

2xb = -4x

b = -2

Step 3

Take square of b and add it to each side of the equation.

x²- 4x + (-2)²= 7 + (-2)²

x²- 4x + 4 = 7 + 4

x²- 4x + 4 = 11

Step 4

Factor the perfect trinomial square

(x−2)² = 11

Step 5

take square root on both sides

√(x−2)² = √11

(x-2) = ±√11

x = ±√11 +2
