Find the missing segment in the attached image

Mathematics
1 answer:
Digiron [165]3 years ago
4 0

Answer:

49 unit.

Step-by-step explanation:

concept used: basic proportionality theorem,

theorem states that, if a line is drawn parallel to one side of the triangle and intersect the other two sides then the two sides are divided in the same ratio.  

Example:

let there be a triangle ABC

if DE is drawn parallel to BC such that D is a point on line AB and E is other point on AC, then

AD/DB = AE/EC (basic proportionality theorem)

_____________________________________

Similarly in this problem ,

one side has length of 60 units,

The parallel line divides it at point such that one of the segment of this side is of 35 units.

Then other segment of same side = 60-35 = 25

now using basic proportionality theorem

?/35 = 35/25

=> ?/35 = 7/5

=> ? = 7/5 * 35 = 49

Thus, length of missing side segment is 49 unit.

Step-by-step explanation:

1-(sin(A)+cons(A))^2

1-(sin(A)^2+2sin(A)cos(A)+cos(A)^2) :use FOIL to get it

1-(1+sin(2A))

1-1-sin(2A)

Solve for h.<br> -12h + 4 = 0
tatuchka [14]

Answer:

h=1/3

Step-by-step explanation:

So we have the equation:

-12h+4=0

Subtract 4 from both sides:

(-12h+4)-4=(0)-4\\-12h=-4

Divide both sides by -12:

(-12h)/-12=(-4)/-12\\h=-4/-12

Simplify and reduce:

h=1/3

Daphne bought a house for 335,000. She financed 276,475 of the purchase price with a 30 year, fixed rate mortgage with 5.65% int
sweet-ann [11.9K]
First find the yearly payment using the formula of the present value of annuity ordinary
The formula is
Pv=pmt [(1-(1+r)^(-n))÷r]
Pv present value 276475
Pmt yearly payment ?
R interest rate 0.0565
N time 30 years

Now solve for pmt
The formula change to be
Pmt=pv÷ [(1-(1+r)^(-n))÷r]
Plug in the equation above
Pmt=276,475÷((1−(1+0.0565)^(−30))÷(0.0565))=19,339.22

Now find the cost of the principle and interest after 30 years by multiplying the yearly payment by the time

19,339.22×30=580,176.60...answer

Hope it helps:-)
