PLS HELP!!<br><br> What values of u and v make triangle XYZ = Triangle GFH
Katarina [22]

Answers:

u = 18

v = 20

========================================================

Work Shown:

The leg YZ is congruent to the left FH

This means YZ = FH and that leads to u+v-18 = 10u-8v

The hypotenuse ZX is congruent to the hypotenuse HG

This means ZX = HG and we get the equation 14v-14u+32 = v+u+22

----------------------

The system of equations we have so far is

u+v-18 = 10u-8v

14v-14u+32 = v+u+22

Let's get the equations into standard form

Start with the first equation

u+v-18 = 10u-8v

u+v = 10u-8v+18

u+v-10u+8v = 18

-9u+9v = 18

-9(u-v) = 18

u-v = 18/(-9)

u-v = -2

Note how we can solve for the variable u to get

u = v-2

which we'll use later

----------------------

Let's get the other equation into standard form as well

14v-14u+32 = v+u+22

14v-14u-v-u = 22-32

-15u+13v = -10

Now plug in u = v-2 and solve for v

-15u+13v = -10

-15(v-2) + 13v = -10

-15v+30+13v = -10

-2v+30 = -10

-2v = -10-30

-2v = -40

v = -40/(-2)

v = 20

Which means,

u = v-2

u = 20-2

u = 18

What is the area of the triangle? 5 in. 3 in 4in O 6 square inches O 7-square inches O 10 square inches O 12 square ches ​
WARRIOR [948]

Answer:

-------------------Heya Kjowanpreet!--------------

\large{ \tt{ \star\: S \: O \: L \: U \: T \: I \: O \: N : }}

GiveN :

  • Sides of the triangle : 3 in , 5 in and 4 ft

To FinD :

  • Area of the provided right angled triangle

FormulA :

  • Area of right angled triangle = 1/2 b × p where b = base & p = perpendicular. Here , Perpendicular = 3 in and base = 4 in

SolvinG :

\large{ \boxed{ \bf{Area \: of \:right \: angled \: triangle : \frac{1}{2} b \times p  }}}

\longrightarrow{  \tt{} \frac{1}{2}  \times 3 \times 4}

\longrightarrow{ \boxed{ \tt{6 \: in ^{2} }}}

  • Yay ! Finally , We solved. Our final answer is 6 square inches.

-5x + 11 = -8(4 + 6x) What are the steps?
Bad White [126]

Answer:

x =  - 1

Step-by-step explanation:

- 5x + 11 =  - 8(6x + 4)

=  >  - 5x + 11 =  - 48x - 32

Lets keep the variable terms in L.H.S. and the constant terms in R.H.S.

=  > 48x - 5x =  - 32 - 11

=  > 43x =  - 43

Lets divide 43 on both the sides.

=  >  \frac{43x}{43}  =  \frac{ - 43}{43}

=  > x =  - 1
