Answer:
equilateral and acute
Step-by-step explanation:
The dashed lines on the sides of the triangle mean that they are all equal in length. Each angle is 60 degrees as represented by the curved lines inside of the triangle. If an angle is less than 90 degrees it's an acute angle.

Zoe, 12 Volumes + 2Vol/Week
Ella, 0 Volumes + 3Vol/week
- So Ella has to catch up 12 Volumes from the start
since ella reads 3 Vol/week which is 1 more than Zoe per week, She will take 12 weeks to read the 12 volumes zoe read
So on 12th week they will read the same amount of books
(On the 12th week) Volumes read =
Z : 12 + 2(12)=36
E: 0 + 3(12) = 36.
They will have read Volume 36, and this will take 12 weeks.
Hope this helps. If you need anymore help just let me know
Answer:
The minimum distance x that a plant needing full sun can be placed from a fence that is 5 feet high is 4.435 ft
Step-by-step explanation:
Here we have the lowest angle of elevation of the sun given as 27.5° and the height of the fence is 5 feet.
We will then find the position to place the plant where the suns rays can get to the base of the plant
Note that the fence is in between the sun and the plant, therefore we have
Height of fence = 5 ft.
Angle of location x from the fence = lowest angle of elevation of the sun, θ
This forms a right angled triangle with the fence as the height and the location of the plant as the base
Therefore, the length of the base is given as
Height × cos θ
= 5 ft × cos 27.5° = 4.435 ft
The plant should be placed at a location x = 4.435 ft from the fence.
The length of each side would be 3 square meters
