Answer:
The answer is:
Step-by-step explanation:
Given:
In △ABC:
m∠A=15°
a=10 and
b=11
To find:
c = ?
Solution:
We can use cosine rule here to find the value of third side c.
Formula for cosine rule:
Where
a is the side opposite to
b is the side opposite to
c is the side opposite to
Putting all the values.
The answer is:
Answer:
BC = 26
Step-by-step explanation:
Given that:
B is the midpoint of AC
Then AC = AB + BC
AC = 8x - 20 and AB = 3x - 1
Then,
8x - 20 = (3x - 1) + BC
8x - 20 - (3x - 1) = BC
8x - 20 - 3x + 1 = BC
5x - 19 = BC
But AB = BC
5x - 19 = 3x - 1
5x - 3x = - 1 + 19
2x = 18
x = 9
Hence,
Since BC = AB = 3x - 1
3(9) - 1
27 - 1
= 26
Answer:
Option 2) y = 26
Step-by-step explanation:
We are given the following in the question:
The individual wants to have two hot dogs for each guest, and 6 extra hot logs in case some teammates bring friends.
Thus, the dependent variable is the number of hot dogs.
The independent variable is the number of teammates.
Thus, the linear relation between the dependent and the independent variable is given as:
We have to find the value of dependent variable when independent variable is 10
For x = 10
Thus, the correct answer is
Option 2) y = 26
