Both equal g(x) so put them together

-x+5=3 then solve for x

-x=3-5
-x=-2
-2 divided by -x =2

Give triangle TRY, find TY. Round your answer to the nearest hundredth.
3241004551 [841]

The length of TY is 2.26.

Solution:

In ΔTRY, θ = 37°, Adjacent side = 3.

To find the length of TY.

Using trigonometry identity,

$\tan\theta=\frac{{opposite}}{{Adjacent}}

$\tan37^\circ=\frac{{TY}}{3}

$3\tan37^\circ=TY

$3\times 0.75355=TY

$TY=2.26065

TY = 2.26

Hence the length of TY is 2.26.

determine whether the lines intersect and if so find the point of intersection and the cosine of the angle of intersection x=4t+
Fittoniya [83]

Answer:

As the lines are not intersecting nor parallel, they must be skew.

Step-by-step explanation:

Question is incomplete, we consider the nearest match available online.

Parametric equations of two lines are:

L₁ : x=4t+2 , y = 3 , z =-t+1

L₂: x=2s+2 , y= 2s+5 , z = s+1

If lines are parallel then parametric coordinates must be equal scalar multiple of each other which s not true here.

4t+2=2s+2 ---(1)\\ \\3=2s+5---(2) \\\\-t+1=s+1---(3)

If lines are intersecting then parametric coordinates must be equal for some value of t and s.

From (3)\\-t=s\\From (2)\\\\s=\frac{3-5}{2}\\\\s=-1\\\implies t=1\\\\To\,\,check\,\, the \,\,values \,\,of \,\,s\,\, and \,\,t \,\,for\,\,intersection\,\,put \,\,them\,\, in\,\, (1)\\\\4(1)+2= 2(-1)+2\\ 6\ne0

Hence the lines are not intersecting nor parallel, they must be skew.

<h2>Hello!</h2>

The answer is:

The area of this figure is 946 square inches.

<h2>Why?</h2>

We can see that the figure is composed by two rectangles with diferrent dimensions, so, to calculate the area of the entire figure.

So,

For the first rectangle, we have:

Base=7in\\Height=28in

The area will be:

Area=Base*Height=7in*28in=196in^{2}

For the second rectangle, we have:

Base=25in\\Height=30in

The area will be:

Area=Base*Height=30in*25in=750in^{2}

Now, calculating the area of the entire figure, we have:

TotalArea=FirstRectangleArea+SecondRectangleArea\\\\TotalArea=196in^{2}+750in^{2}=946in^{2}

Have a nice day!
