How do I fine the perimeter of these triangles?
arsen [322]

constant of proportionality => COP

3: P(triangle ABC) = 84

COP = 18/15 = 1.2

Since you are finding the larger triangle, multiply the other numbers by 1.2

25 * 1.2 = 30

28 * 1.2 = 33.6

17 * 1.2 = 20.4

add them all up (answer up top)

5: P(triangle ABC) = 61.2

COP = 9/5 = 1.8

Since you are finding the larger triangle, multiply the other numbers by 1.8

9 * 1.8 = 16.2

13 * 1.8 = 23.4

12 * 1.8 = 21.6

add them all up (answer up top)

6: P(triangle RST) = 110

RP and PT are congruent, this means that PT is also 20

COP = 40/20 = 2

Since you are finding the larger triangle, multiply the other numbers by 2

25 * 2 = 50

20 * 2 = 40

10 * 2 = 20

add them all up (answer up top)

Determine the ratio in which the point (–6, m) divides the join of A(–3, –1) and B(–8, 9). Also, find the value of m.
PSYCHO15rus [73]

Answer:

Ratio = 3 : 2 and value of m = 5.

Step-by-step explanation:

We are given the end points ( -3,-1 ) and ( -8,9 ) of a line and a point P = ( -6,m ) divides this line in a particular ratio.

Let us assume that it cuts the line in k : 1 ratio.

Then, the co-ordinates of P = ( \frac{-8k-3}{k+1},\frac{9k-1}{k+1} ).

But, \frac{-8k-3}{k+1} = -6

i.e. -8k-3 = -6k-6

i.e. -2k = -3

i.e. k = \frac{3}{2}

So, the ratio is k : 1 i.e \frac{3}{2} : 1 i.e. 3 : 2.

Hence, the ratio in which P divides the line is 3 : 2.

Also, \frac{9k-1}{k+1} = m where k = \frac{3}{2}

i.e. m = \frac{\frac{9 \times 3}{2}-1}{\frac{3}{2}-1}

i.e. m = \frac{27-2}{3+2}

i.e. m = \frac{25}{5}

i.e. m = 5.

Hence, the value of m is 5.
