Examine the diagram.<br> What is the value of x?
allochka39001 [22]

Answer:

x = 10

Step-by-step explanation:

Since two angles lie on line M, we know that their sum will be equal to 180. Since we know one the their angles, we subtract 136 from 180 and get 44.

We also know that the sum of all a triangle interior angle together equal 180. We all ready have two of those angles so we can now find the third.

44 plus 90 equals 134.

180 minus 134 equals 46. So now we know the measurement of the last angle.

Now to we have to solve for x.

We know that 4x+6 equal 46, since they both represent the angle of angle L.

Once you solve 4x+6=46, you will get x = 10.

Answer: x = 10

I'm confused.<br> I have to convert 16°f to C° using the formula f=1.8C+32 .<br> How to do that ?
SashulF [63]

Answer:

16 °F = -8.89 °C

Step-by-step explanation:

Given:

Temperature is Fahrenheit is, F= 16° F

The formula that relates Fahrenheit and Celsius is:

F=1.8C+32

Express this in terms of Celsius C. This gives,

C=\frac{F-32}{1.8}

Plug in 16 for F and solve for C. This gives,

C=\frac{16-32}{1.8}=\frac{-16}{1.8}=-8.89

Therefore, 16 °F is equal to -8.89 °C.

The height of the tunnel at the center is 35ft, and the vertical clearance must be 21 ft at a point of 8ft from the center. Find
Zinaida [17]

Answer:

y=-0.215x^2+35

Step by Step:

Let, h=0,  k=35, x=8, y=21

We know that, the general equation of the parabola.

   y-k = a(x-h)^2

\Rightarrow y=a(x-h)^2+k  .........(i)

Substitute the  value of h, k, x, y in equation (i) and find the value of a.

  21=a(8-0)^2+35

\Rightarrow 21=a\times 8^2+35

\Rightarrow 21=64a+35

\Rightarrow 64a=21-35

\Rightarrow 64a=-14

\Rightarrow a=\frac{-14}{65}

\Rightarrow a=-0.215

Hence, the equation of the parabola is:

y=-0.215x^2+35
