The answer b= 2h
the angle opposite to its base is a
so sina = b/2h= b/b=1
the answer is <span>b) 1</span>
Answer:
d
Step-by-step explanation:
f(3)=5(3)²-7(4(3)+3))
=45-105
= -60
Answer:
15.59
Step-by-step explanation:
The answer is 15.59 because to find the area of an equilateral triangle, you need to multiply the height by the length. In this scenario, the length is 6, and we need to find the height. Since we know that all of the sides of the equilateral triangle are 6, we can put a line dividing the equilateral triangle exactly in half as our height. This will form 2 triangles, and each of them will have a length of 3, and a slant height of 6. They would also be right triangles. Now, with this information you can do pythageroum thereom to find the height:: 3^2 + h^2 = 6^2. So, h = √27. Now, to find the area of a triangle, you must multiply the length by the height and then divide by 2. So (6 • √27)/2 is equal to 15.5884572681, which rounded is equivalent to 15.59. So the answer is 15.59.
Divide 20 by 2
20/2 = 10
Add and subtract 0.5* from 10
10 + 0.5 = 10.5
10 - 0.5 = 9.5
Those two numbers are your answer.
*The reason why we used 0.5 because the difference is 1, so divide 1 by 2.
Have an awesome day! :)
