Answer:

199 in.

Step-by-step explanation:

We already now what the bottom two sides lengths are but we need to find the length of the top 2 sides.

To find the side lengths we can use the area of the right triangle on the top with the area of 15 in. to do that we need to find the lengths of the two dotted red lines making the right triangle using process of elimination the lengths of the left side is 3 the bottom length is 10. the we use the Pythagorean theorem to find the length of the perimeter. 10^2+3^2=109 109/2= 54.5. the length of the top two sides are 54.5. To now find the perimeter we add the length of one of the top 54.5 and one of the bottom 45 to get 99.5 then multiply it by 2 99.5*2= 199 the perimeter of the window is 199 in.

A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20in
Rom4ik [11]

Answer:

100 inches

Step-by-step explanation:

A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20inches. Find the perimeter of the larger triangle.

This is calculated using proportion

Side length/Perimeter

Hence:

Side length of smaller triangle = 19 inches

Perimeter of smaller triangle = 95 inchee

Side length of larger triangle = 20 inches

Perimeter of larger triangle = x

19/95 = 20/x

Cross Multiply

19x = 95 × 20

x = 95 × 20/19

x = 100 inches

The perimeter of the larger triangle = 100 inches

Sara goes to a furniture store to buy a dining set, end tables, and a loveseat. She sees a lamp for $40 and an end table for $62
BaLLatris [955]

Answer:

$1191.60

Step-by-step explanation:

<u>Option 1:</u>

Leather Loveseat

1200 plus 2% extra charge and NO TAX

What is 2% of 1200??

0.02 * 1200 = 24

So total price = 1200 + 24 = $1224

<u>Option 2:</u>

Lush Blue Loveseat and Lamp

Lush Blue loveseat is 980 + 17% tax, that would be worth 980 + (0.17)(980) = $1146.6

and

lamp is worth 40 with 12.5% tax, that would be worth 40 + (0.125)(40) = $45

Total cost = 1146.6 + 45 = $1191.6

2nd option is cheaper, so that would cost $1191.60

Can you help me solve this please step by step
eimsori [14]
First, the values of 2sqrt(3) or 3sqrt(3) are not even twice the length of the given base, 3.

Next, I would say that 6 is the better answer than 12, assuming that the triangle is”drawn-to-scale”.

Finally, I think the hypotenuse is 6.
