Please help quick!! <br> Given ΔΡHS &amp; ΔCNF, find the values of x, y, and z.
valkas [14]

Answer:

x=24, y=10, z=17

Step-by-step explanation:

We know that \Delta PHS\cong\Delta CNF.

Then by CPCTC, ∠P≅∠C, ∠H≅∠N, and ∠S≅∠F.

Therefore, let’s solve for each of the angle relations.

∠P≅∠C:

We know that ∠P is 36°. ∠C is (4z-32)°. Therefore:

36=4z-32

Solve for z:

\begin{aligned}36&=4z-32\;\;\; \text{Add 32 to both sides}\\68&=4z\;\;\;\;\;\;\;\;\;\;\;\text{Divide both sides by 4}\\17&=z\end{aligned}

So, the value of z is 17.

∠H≅∠N

∠H is (6x-29) and ∠N is 115. So:

6x-29=115

Solve for x:

\begin{aligned} 6x-29&=115\;\;\;\;\;\;\text{Add 29 to both sides}\\6x&=144\;\;\;\;\;\;\text{Divide both sides by 4}\\\ x&=24\end{aligned}

Therefore, the value of x is 24.  

∠S≅∠F

We will need to find ∠S.

We already know that ∠P is 36.

∠H will be (6x-29). Substitute 24 for x to acquire: (6(24)-29)=144-29=115.

A triangle always totals 180°. Therefore, 115+36+∠S=180 or 151+∠S=180.

Therefore, ∠S=29.

∠F is (3y-1). So:

29=3y-1

Solve for y:

\begin{aligned} 29&=3y-1\;\;\;\;\;\text{Add 1 to both sides}\\ 30&=3y\;\;\;\;\;\;\;\;\;\;\text{Divide both sides by 3}\\ 10&=y\end{aligned}

Therefore, the value of y is 10.

So, x=24, y=10, and z=17.

And we are done!

What is (4m+9)−3(2m−5)
grandymaker [24]

Answer: −2m+24

Step-by-step explanation

  • Distribute:

4m+9+(−3)(2m)+(−3)(−5)

4m+9+−6m+15

  • Combine like terms:

4m+9+−6m+15

(4m+−6m)+(9+15)

−2m+24

A rectangular building lot has a width of 59.0 ft and a length of 132 ft. determine the area of this lot in square meter
vazorg [7]

Answer:

  723.53 m^2

Step-by-step explanation:

The area is the product of the width and length. Each foot is 0.3048 meters, so the area in square meters is ...

  (59 ft·0.3048 m/ft)·(132 ft·0.3048 m/ft) ≈ 723.53 m^2
