Answer:
The side lengths are 30, 36 and 39.
Step-by-step explanation:
To find the missing side, write a proportion using side lengths from each similar shape. A proportion is an equation that sets equal two ratios.

Find y by cross multiplying numerator and denominator of each fraction.
13y = 39(12)
13y = 468
y = 36
Find the other missing side by repeating the process.

Find y by cross multiplying numerator and denominator of each fraction.
13y = 39(10)
13y = 390
y = 30
The side lengths are 30, 36 and 39.
<span>Based on the lengths given, 6 cm, 10 cm and 12 cm, the classification that best describes the triangle is that "It is a Scalene triangle." A scalene triangle is a type of triangle whose sides are not of the same length. </span>
Answer:
40% of the total was spent on fruit
Step-by-step explanation:
100%=45 x=18
100/x = 45/18 Now take the inverse of both sides
x/100 = 18/45
This leads to 1800 = 45x
1800 divided by 45 is equal to 40
The total percentage spent on fruit was 40%
