What is the value of x? ​

Mathematics

Alecsey [184]2 years ago

Answer:

The value of x is 104

Step-by-step explanation:

we are given 52 we know that 52 is within an isosceles triangle.

which means 2 sides are the same which tells us that the two angles touching the unique side will have the same measure

we also know that a triangle adds up to 180 so 52 + 52 gives us 104 meaning the last angle will be 180 - 104 which is 76

now we have completed the first triangle if

if we look at corner c we know that it's a right angle

we know that right angles are a total of 90 degrees we know that the right angle is split into two complementary angles one of them is 52 which we figured from the first part so

90 - 52 would give us 38 now we know that in triangle CDE one of the measures is 38 at the c corner and another is 90 at the E corner

once again we do 90 + 38 = 128 and subtract that from 180 giving us 52.

Now we know the measures of triangle ADC and CDE

We also know that triangle EDB is a congruent mirror reflection of CDE

So by now we have the measures of 3 triangles CDE ADC AND EDB

we also know that angle F/x is equvilant to the total of both of angle D

so we just add 52 + 52 giving us the measure of the whole angle d combined which we know is eqivilant to angle f

So after all that we know that the value of x is 104 degrees.

Hope this helps its a long explanation but please take ur time to understand and read through it :)

1 US Dollar =13.05 pesos 1meter =1.094 yars
Evgesh-ka [11]

Answer:

$18.01

Step-by-step explanation:

Convert from pesos to US dollars

6429/13.05 = $492.64

Convert from meters to yards

1.904* 25= 27.35

Divide to find the cost of one yard of fabric

492.64/27.35 = $18.01

Without solving determine the number of real solutions for each quadratic equation
seropon [69]

Answer:

b^2-4b+3=0

b²-3x-b+3=0

b(b-3)-1(b-3)=0

(b-3)(b-1)=0

either

b=3 or b=1

.

2n^2 + 7 = -4n + 5

2n²+4n+7-5=0

2n²+4n+2=0

2(n²+2n+1)=0

(n+1)²=0/2

:.n=-1

.

x - 3x^2 = 5+ 2x - x^2

0=5+ 2x - x^2-x +3x^2

0=5+x+2x²

2x²+x+5=0

comparing above equation with ax²+bx +c we get

a=2

b=1

c=5

x={-b±√(b²-4ac)}/2a ={-1±√(1²-4×2×5)}/2×1

={-1±√-39}/2

Use the midpoint formula to estimate the sales of Cars, Inc. in 2009, given the sales in 2008 and 2010. Assume that the sales of
lana [24]

Answer:

<em>The estimated sales were $260 million</em>

Step-by-step explanation:

Assume the endpoints of a segment are (x1,y1) and (x2,y2).

The midpoint (xm,ym) is calculated as follows:

\displaystyle x_m=\frac{x_1+x_2}{2}

\displaystyle y_m=\frac{y_1+y_2}{2}

The sales ov Cars, Inc. were (2008,240 million) and (2010,280 million). We need to use the midpoint to estimate the sales in 2009:

\displaystyle x_m=\frac{2008+2010}{2}=2009

\displaystyle y_m=\frac{240+280}{2}=260

The estimated sales were $260 million
