Hey there :) I'm pretty sure that your answer is D) ∠S ≅ <span>∠Y because corresponding angles of similar triangles are congruent.

I think that it is the answer because if you shift your paper around, and look at the angles from different views, you can tell that angles S and Y are congruent, or the same, because of the way that both angles are at the end of the longer sides of both triangles.

So, your answer is D!

~Hope this helped!~</span>

What is liner equation with two variable?

  • An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
  • For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.

-10x² -10y² = -300 ----a

5x² + 5y² = 150 ---- b

While trying to solve this,

We can multiply the eq. b by 2 so we will get eq. c and then add to eq. a we will get 0 as the solution.

10x² + 10y² = 300 ----c

-10x² -10y² = -300 ---a

<u>Everything cutoff, we will </u><u>get 0</u><u>, and there is no solution to these equations.</u>

Can anyone help me solve this.I need proper equation..Thanks​

Answer:

y = 9\sqrt{2}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = \frac{1}{\sqrt{2} }

sin45° = \frac{opposite}{hypotenuse} = \frac{9}{y}

Multiply both sides by y

y × sin45° = 9, that is

y × \frac{1}{\sqrt{2} } = 9

Multiply both sides by \sqrt{2}

y = 9\sqrt{2}

Can someone please help me with this?

Answer:

e = 29.0 will be the answer.

Step-by-step explanation:

Use the sine rule in the given triangle,

\frac{EF}{\text{sin}(\angle D)}=\frac{DE}{\text{sin}(\angle F)}=\frac{DF}{\text{sin}(\angle E)}

\frac{d}{\text{sin}(35)}=\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}

d=\frac{16\times \text{sin}(35)}{\text{sin}(30)}

d = 18.35

\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}

e=\frac{16\times \text{sin}(115)}{\text{sin}(30)}

e = 29.002

e ≈ 29.0

Therefore, e = 29.0 will be the answer.

Find the area and perimeter.
lara [203]

Answer:

Step-by-step explanation:

Perimeter of triangle =  4x - 3 + x + 9 + 8

                                   = <u>4x + x</u> -<u> 3 + 9 + 8</u>

                                  = 5x + 14

Area  = \frac{1}{2}*base *height

         = \dfrac{1}{2}*8*3x\\\\= 4 * 3x\\\\= 12x
