Imagine removing the segment SP, what is the angle m∠RST?

m∠RST = 15x -10

Then,  the segment SP divides the angle m∠RST in two, m∠RSP and m∠PST and we know the corresponding values (in terms of x obviously). Now, each line is a way to express the situation.

m∠RST = m∠RSP + m∠PST (by Angle Addition Postulate).

15x - 10 = (x +25) + (5x +10)\\

Then, with some of algebra, we obtain

15x - 10 = 5x+35

9x = 45

x = 5



7. <u><em>Adjacent angles:</em></u> Two angles are Adjacent when they have a common side and a common vertex (that is the corner point) and don't overlap.

<u><em>Opposite angles: </em></u><em> </em> When two lines intersect, four angles are formed. The angles that are directly opposite to each other are called Opposite Angles


8. m∠LMN = 2 m∠LMP. But  The Lienar Pair says that: Two angles that are adjacent (share a leg) and supplementary (add up to 180°). Then   m∠LMN + m∠LMP = 180, so

2 m∠LMP + m∠LMP = 180, then

m∠LMP = 60

Translate this sentence into an equation.
kakasveta [241]

Answer:

21+j=55

Step-by-step explanation:

It says sum, which means to add(+). So you add 21 and j (21+j) and that equals 55 (=55). Then you add all the pieces together and you get 21+j=55

Assume you are given two right triangle with congruent hypotenuses and wish to show that they are congruent
uysha [10]
If you can find one leg of a triangle to be congruent to a leg on the other triangle, then you can use the HL (hypotenuse leg) theorem. If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.

What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio
aalyn [17]

Answer:

  StartFraction 6 Over 5 x Superscript 10 Baseline EndFraction

Step-by-step explanation:

Apparently you want to simplify ...

  \sqrt{\dfrac{72x^{16}}{50x^{36}}}

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  1/a^b = a^-b

  (a^b)^c = a^(bc)

__

So the expression simplifies as ...

  \sqrt{\dfrac{72x^{16}}{50x^{36}}}=\sqrt{\dfrac{36}{25x^{36-16}}}=\sqrt{\dfrac{36}{25x^{20}}}\\\\\sqrt{\left(\dfrac{6}{5x^{10}}\right)^2}=\boxed{\dfrac{6}{5x^{10}}}

1.) You are one of five people who have been hired to mow the lawn at the local college. Each week, the dimensions of the plot y
iren [92.7K]

Answer:

1a)  Length = 7x + 3  & Width = 4x - 2

1b)  Area = 28x^2 -2x -6

1c)  Area = 2774 sq. m

2.  (x-4)(y+7)

Step-by-step explanation:

1a)

The length given as words is "3 more than 7 times x"

The width given as words is "4 times x minus 2"

The expression for length would be  7x + 3

The expression for width would be 4x - 2

1b)

The area is length * width

Since we already know the algebraic expressions for length and width from part (a) above, we use the formula:

Area = (7x+3)(4x-2) = 28x^2 -14x + 12x - 6 = 28x^2 -2x -6

Area = 28x^2 -2x -6

1c)

Given x = 10, we put this into the area expression we found in (b) above.Let's see:

28x^2 -2x -6\\=28(10)^2 -2(10) -6\\=2774

Area = 2774 sq. m

2.

We can group the first two terms and next two terms and write up:

xy-4y+7x-28\\(xy-4y)+(7x-28)\\y(x-4)+7(x-4)\\(x-4)(y+7)

That's the factored form.
