ABC is isosceles with AB=AC=8 units and BC=6 units. D and E are midpoints of AB and BC respectively. Calculate the length of DE?
1 answer:
The triangle is drawn and is shown in the image attached with.
We get two similar triangles. Triangle ABC and Triangle ADE. Since the triangles are similar the ratio of their corresponding sides will be the same.
D and E are the midpoints of AB and BC, therefore, AD and AE are both 4 units in length. Using the property of similar triangles, we can say:
AD : DE= AB : BC
AD = 4 units
AB = 8 units
BC = 6 units
DE = unknown = x units
So,
Therefore, the length of DE will be 3 units

Answer:
Cristiano will have enough money to buy bike in 9 weeks.
Step-by-step explanation:
Given:
Cost of the bike = $189
Money saved = $99
Money saving each week = $10
We need to find the number of weeks will he have money to buy bike.
Solution:
Let the number of weeks be 'x'.
Now we can say that;
Money saved plus money saving each week multiplied by number of weeks is equal to cost of the bike.
framing in equation form we get;
Subtracting both side by 99 using subtraction property of equality we get;
Dividing both side by 10 using division property of equality we get;
Hence Cristiano will have enough money to buy bike in 9 weeks.
Answer:
539
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
Where a₁ is the first term and d the common difference
Here a₁ = 8 and d = 17 - 8 = 26 - 17 = 9, thus
= 8 + (9 × 59) = 8 + 531 = 539
