AM is a median in △ABC (M∈ BC ). A line drawn through point M intersects AB at its midpoint P. Find areas of △APC and △PMC, if A

Snowcat [4.5K]

Answer:

The area of APC is 70m². The area of triangle PMC is 35m².

Step-by-step explanation:

Let the area of triangle ABC be x.

It is given that AM is median, it means AM divides the area of triangle in two equal parts.

$\text{Area of }\triangle ACM=\text{Area of }\triangle ABM=\frac{x}{2}$ .....(1)

The point P is the midpoint of AB, therefore the area of APC and BPC are equal.

$\text{Area of }\triangle APC=\text{Area of }\triangle BPC=\frac{x}{2}$ ......(2)

The point P is midpoint of AB therefore the line PM divide the area of triangle ABM in two equal parts. The area of triangle APM and BPM are equal.

$\text{Area of }\triangle APM=\text{Area of }\triangle BPM=\frac{x}{4}$ .....(3)

The area of triangle APM is 35m².

$\text{Area of }\triangle APM=\frac{x}{4}$

$35=\frac{x}{4}$

$x=140$

Therefore the area of triangle ABC is 140m².

Using equation (2).

$\text{Area of }\triangle APC=\frac{x}{2}$

$\text{Area of }\triangle APC=\frac{140}{2}$

$\text{Area of }\triangle APC=70$

Therefore the area of triangle APC is 70m².

Using equation (3), we can say that the area of triangle BPM is 35m² and by using equation (2), we can say that the area of triangle BPC is 70m².

$\triangle BPC=\triangle BPM+\triangle PMC$

$70=35+\triangle PMC$

$35=\triangle PMC$

Therefore the area of triangle PMC is 35m².

Express each fraction as a percent. Round your answer to the nearest whole number.

GREYUIT [131]

Answer:

60.8% which rounds to 61%

42.61% which rounds to 43%

29.14% which rounds to 29%

Step-by-step explanation:

So, there are two ways to do this, either perform the division as you see it, or make it so it is some number over 100 instead of what it is.

For the first one if you just do the division, either with long division or with a calculator you get exactly .608. The other two are not as nice, jsut a warning. From here you multiply it by 100 to get the percent. For instance with .5 (which is half) the corresponding percent is 50%, which is after you multiply .5 by 100). if you need help with the division let me know and I can work you through one.

if we go with the second way we would want to make 125 into 100. To do this we need to multiply it by something to get to 100. Or in other words, 125x=100. This winds up being .8, or 8/10 You could also see it as dividing 125 by 1.25 or 5/4, if you need help with this (or any part in particular really) let me know.

Anyway, since one part of the fraction is being multiplied or divided, the other part does too, so you would take 76 and do the same. Whichever number you use you get 60.8. You don't have to multiply this by 100 since it is already part of a fraction over 100.

Again, let me know if you need more help, I will leave the other two to you unless you need the help.

Please help me with this!!

34kurt

Answer:

36

Step-by-step explanation:

Think of the unknown sized side as a half of 12 and multiply them together when your triangle is obtuse like that. and split the answer from 6 times 12.

I hope this helped you!
