D is the answer to your question
Answer:
B because 8 seeds from pack 1. u do 8 times 3 other packs which is 24 So in between 20-30 seeds will sprout
The value of a=7 will make the equation true
Answer: 16.5
Step-by-step explanation: First do 8 times 3 then divide by 264=16.5. I think this is the answer
The answer is: The first triangle. The reasons are shown below:
1. All the triangles are rigth triangles, because they have an angle of 90°. So, let's calculate the others angles of the first one:
Tan(α)^-1= opposite leg/adjacent leg
Opposite leg=5
Adjacent leg=5√3
Tan(α)^-1= 5/5√3
Tan(α)^-1=30°
2. Let's calculate the other angle:
Tan(α)^-1= opposite leg/adjacent leg
Now, the opposite leg will be 5√3 and the adjacent leg will be 5. Then:
Tan(α)^-1= 5√3/5
Tan(α)^-1=60°
As you can see, the angles of first triangle are: 30°,60° and 90°.
