we know that

we know that

<u>Vertical angles</u> are congruent angles opposite each other where two lines cross

so

in this problem

m∠JNM=m∠KNL

so

substitute the values

4x+6=7x-21\\7x-4x=6+21\\3x=27\\x=27/3\\x=9\°

<u>Find the  m∠JNM</u>

(4x+6)=(4*9+6)=42\°

therefore

<u>the answer is</u>

The measure of angle JNM is 42\°

How do you solve y=2x+7; 3x-y=-9 using substitution method. Explain please!!
eduard
The y's value is given in the first equation. y=2x+7 . Now to solve, we will, plug it's value in the second equation.

3x-(2x+7)=-9\\ \\ 3x-2x-7=-9\\ \\ x=-9+7\\ x=-2\\

Now we have x's value, we will plug it's value in the first equation.(We can plug it in the second one too, but plugging it the first one will make it easier.)

x=-2\\ y=2x+7\\ y=2\cdot -2+7\\ y=-4+7\\ y=3

PLZZZZ HELPPPPPP THIS IS TIMEDDDD!!!! *look at picture*
Kazeer [188]

Answer:

Height of the building = 50.8 ft

Step-by-step explanation:

A person and a building are casting the shadows at the same time of the day.

Triangles formed by the person and his shadow and the building and its shadow will be similar.

Therefore, corresponding sides of the similar triangles will be proportional.

\frac{x}{28}=\frac{5.8}{3.2}

x = \frac{5.8\times 28}{3.2}

x = 50.75

x ≈ 50.8 ft
