Jawab

Dinda received a 32% loss percentage.

Step-by-step explanation:

The question in English is

Dinda bought a phone for Rp.2,500,000.00. After 5 months, she sells it with

the price of Rp1,700,000.00. What percentage of losses did Dinda receive?

we know that

Rp.2,500,000.00 represent the 100%

so

Using a proportion

Find out what percentage represent the difference between the original value and the final value

therefore

Dinda received a 32% loss percentage.

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
