Answer:
Step-by-step explanation:
The given function is
and the inverse function is
To find f(2), we substitute x=2 into the function f(x)=½x
This implies that,
Similarly,
Based on the above results,
Answer:
3
Step-by-step explanation:
Answer:
Angle DBF = 92 degrees
Step-by-step explanation:
From the information given, we can see that we can use the triangle mid segment theorem and conclude that all 4 small triangles are congruent to each other. Therefore, all corresponding angles are also congruent to each other. Since DBF and EFC are corresponding angles and we already know that EFC is 92 degrees, DBF must also be 92 degrees.
Answer:
Step-by-step explanation:
30-60-90 triangle.
Side opposite to 30 = a
Side opposite to 60 = a√3
Side opposite to 90 = 2a
Now,
Side opposite to 30 = 17
So, x = 17√3
y = 2*17 = 34
