Step-by-step explanation:
Find the 3rd angle in the triangle, let's call it y
36 + 73 + y = 180
109 + y = 180
y= 71
y is equivalent to x by vertical angles theorem
x= 71
2nd way
Use exterior angles theorem
180 - (36+73) = x
180 - 109 = x
71 = x
I hope this helps!!!
Answer:
The cost of one sandwich is $15 and the cost of one salad is $5
Step-by-step explanation:
<u><em>The question is</em></u>
Find out the cost of one sandwich and the cost of one salad
Let
x ----> the cost of one sandwich
y ---> the cost of one salad
we know that
-----> equation A
-----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
using a graphing tool
the solution is the point (15,5)
see the attached figure
therefore
The cost of one sandwich is $15 and the cost of one salad is $5
Choosing 3 persons out of the four persons available in for the committee, we use the concept of combination,
4C3 = 4
The statements that are true for this item are: A, B, and D.
4 to the second power is 16 and 3 to the third power is 27 so 27-16=11. Four to the second power is basically 4x4 and three to the third power is 3x3x3
