Two triangles are similar.The the smaller triangle has side 10,20 and 15 units the larger triangles longest side is 52 units.Wha
Oliga [24]

Answer: The perimeter of the largest triangle = 117 units.

Step-by-step explanation:

Sides of smaller triangle = 10,20 and 15 units

Longest side = 20 units

Longest side of larger triangle = 52 units

Sides of two similar triangles are proportional.

Let k be proportionality constant.

k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}

k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}

Length of other two sides,

10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}

So sides of larger triangle = 52 units, 26 units , 39 units

Perimeter of largest triangle = 52 +26+39 = 117 units

Hence, the perimeter of the largest triangle = 117 units.

Find the perimeter of the track. Make<br> sure to include units.<br> 15 yards<br> 25 yards
ahrayia [7]

Answer:

Assuming that it's a rectangular track and the units are 15x25 yards, the perimeter is 80 yards.

Explanation:

Remember to find the perimeter of a non-circular shape you just add up all of the side lengths together. In this case, I believe it's a 15x25 yard rectangle, so you ad 15 + 15 + 25 + 25 to get a total of 80 yards.
