Angle I measured 20 degrees, side HI = 5, angle L = 20 degrees, and side KL =5. What additional information would you need to pr
Artist 52 [7]

Answer:

IJ = LM.

Step-by-step explanation:

The Side-angle-side postulate states that if the pair of a corresponding sides and angles formed between these sides of two triangles are equal in measurement then these two triangle are said to be congruent.

As shown in figure 1 below:

In Δ HIJ and ΔKLM,

∠I = ∠L = 20° and HI = KL = 5 units

Since the ∠I lies between HI and IJ and ∠L lies between KL and LM, ∴ if IJ = LM then Δ HIJ and ΔKLM will be congruent by SAS postulate.

Nancy bought 7 pounds of oranges and 3 pounds of bananas for $17. Her husband later bought 3 pounds of oranges and 6 pounds of b
Serjik [45]

Answer:

<u>The price of oranges is US$ 2 per pound and the price of bananas is US$ 1 per pound.</u>

Step-by-step explanation:

1. Bananas and oranges bought by Nancy:

Oranges = 7 pounds

Bananas = 3 pounds

Cost = US$ 17

2. Bananas and oranges bought by Nancy's husband:

Oranges = 3 pounds or 3x

Bananas = 6 pounds or 6y

Cost = US$ 12

3x + 6y = 12 (Dividing by 3 at both sides of the equation)

x + 2y = 4

x = 4 - 2y

3. Total Purchases:

Oranges = 10 pounds or 10x

Bananas = 9 pounds or 9y

Cost = US$ 29

10x + 9y = 29

10 (4 - 2y) + 9y = 29 (Replacing x with 4 - 2y from 2nd purchase)

40 - 20y +9y = 29

-11y = 29 - 40

- 11y = - 11

y = 1 (Dividing by -11 at both sides)

<u>Pound of bananas = US$ 1</u>

10x + 9 (1) = 29 (Replacing y by 1 in the original formula)

10x + 9 = 29

10x = 20

x = 2 (Dividing by 10 at both sides)

<u>Pound of oranges = US$ 2</u>
