Answer:
{-9,1,11}
Step-by-step explanation:
Just place the domain values to your x value in the function.
The length of the diagonal and the shorter base are 17. 24 feet and 18. 7 feet long respectively.
<h3>How to determine the length</h3>
The cosine rule is given as;
c = length of the diagonal
a = base length = 22 feet
b = 7 feet
feet
Using sine rule
Cross multiply

Answer:
73
Step-by-step explanation:
first u have to subtract 11 and 3 with is 8 and then you have to multiply 8 times 8 which is 64 aqnd then plus 9 and there u get 73
The value of the length DF is 17
<h3>How to determine the length DF?</h3>
The statement Triangle ABC = Triangle ADF means that the triangles ABC and ADF are congruent triangles.
So, we have:
AB = AD
AC = A F
BC = DF
Given that BC = 17;
The equation BC = DF becomes
17 = DF
Rewrite as:
DF = 17
Hence, the value of the length DF is 17

=
equals
k = 15.6
First, simplify
to 1.2. Your problem should look like:
= 1.2
Second, multiply both sides by 13. Your problem should look like: k = 15.6, which is the answer.
