Find x. Then find the measure of angles A, B and C.

mafiozo [28]

Answer:

x= 11

A=59

B= 37

C = 84

Step-by-step explanation:

A triangle adds up to 180 °.

So the equation will be a °+ b° + c° = 180°

Next, you combine like terms.

$6x + 3x + 9x+4-15-7 = 180\\18x-18=180$

Then inverse operation,

$18x-18=180\\18x=198\\x=11$

After to get a, b, and c you just need to plug in x.

$6(11)-7=a\\3(11)+4 = b\\9(11)-15=c$

What is the value of x? Enter your answer in the box. x =

Montano1993 [528]

Answer:

x=9

Step-by-step explanation:

We have two similar triangles because both lines are parallel, use proportions to solve:

$\frac{72}{9} =\frac{56}{3x-20}\\8=\frac{56}{3x-20}\\8(3x-20)=56\\3x-20=7\\3x=27\\x=9$

32^(x+4) = 64^(2x-1)

Rudik [331]

Answer:

Vamos a resolver la ecuación paso a paso.

32x+4=642x−1

Step-by-step explanation:

Resolver el exponente.

32x+4=642x−1

log(32x+4)=log(642x−1)(Sacar el logaritmo de ambos lados.)

(x+4)*(log(32))=(2x−1)*(log(64))

x+4=(

log(64)

log(32)

)*(2x−1)

x+4=1.2*(2x−1)

x+4=2.4x−1.2(Simplificar ambos lados de la ecuación)

x+4−2.4x=2.4x−1.2−2.4x(Restar 2.4x a ambos lados)

−1.4x+4=−1.2

−1.4x+4−4=−1.2−4(Restar 4 a ambos lados)

−1.4x=−5.2

−1.4x

−1.4

=

−5.2

−1.4

(Dividir ambos lados por -1.4)

Explain what needs to be fixed.<br> 2n + 10 = -2<br> 2n = 12 Step one<br> n = 6 Step two

Brilliant_brown [7]

Answer:

step one needs to be fixed... you are supposed to subtract 10 from both sides of the equation.

Step-by-step explanation:

STEP 1: Move all terms not containing n to the right side of the equation.

$2n=-12$

STEP 2: Divide each term by 2 and simplify.

$n=-6$

Parallelogram Property: opposite sides are congruent<br><br> Solve for x.

boyakko [2]

Answer:

Value of x = 19

Step-by-step explanation:

We know that in a parallelogram opposite sides are congruent.

So, in the given parallelogram side LM ≅ side NO

So, we can write $2x+2=40$

Solving the equation to find value of x

$2x+2=40\\2x=40-2\\2x=38\\x=\frac{38}{2}\\x=19$

So, value of x = 19
