In the figure, use similar triangles and the fact that corresponding sides are proportional to find the missing length.​
Phoenix [80]

Answer:

  • <u><em>The missing length, x, is equal to 7 m.</em></u>

Explanation:

In the figure, the two triangles are similar because they show two pairs of congruent angles and one pair of different sides.

  • The two upper vertices are marked each with a line which indicates that they are congruent, i.e. they have the same measure.

  • Also, the small squares shown in each of the bases indicate that those two angles are right, i.e. they measure 90°.

  • Since the two sides adjacent to the right angles have different lengths, the triangles are not congruent but similar.

By similarity, you can state that the corresponding parts keep the same ratio. Thus:

  • x / 8m = 21m / 24m

  • x = 8m × 21 m / 24 m (muliply both sides by 8m)

  • x = 21 m / 3 (simplify dividing numerator and denominator by 8m)

  • x = 7 m (simplify dividing by 3)

         Answer x = 7 m

A shop sells fruit in two types of gift boxes: standard and deluxe. Each standard box contained 1kg of peaches and 2kg of apples
Morgarella [4.7K]
Let's call the number of standard boxes sold x and the number of deluxe boxes sold y.
The kg of peaches sold will be 1 for each standard box and 2 for each deluxe, so we know:
x + 2y = 12
The kg of apples sold will be 2 for each standard box and 1.5 for each deluxe, so:
2x + 1.5y = 14. Now we solve the two equations as a system:
From the 1st one:
x = 12 - 2y
We substitute in the second one:
2(12 - 2y) +1.5y = 14;
24 - 4y +1.5y = 14;
-2.5y = -10;
y = 10/2.5 = 4;
Now we substitute in the first equation:
x = 12 - 2y = 12 - 2*4 = 12 - 8 = 4.
So the shop sold 4 standard boxes (x) and 4 deluxe boxes (y).
