Answer:
The correct option is option A
Step-by-step explanation:
Given two triangles in which ∠B=∠E=50° and AB=DE=10 units.
we have to find the missing condition need to show the two triangles ABC and DEF congruent by AAS.
The condition given are
∠B=∠E
AB=DE
One side and one angle congruent given we need one more angle of both the triangles congruent such that the side does not lies between the two angles.
Hence, the possible angles are ∠C and ∠F.
The correct option is option A

Answer:
21. d. 39
22. c. 20; 7
Step-by-step explanation:
21. This is straightforward evaluation of the function. Put the numbers 8 and -5 where x is in the function definition and do the arithmetic. Then find the difference of the results.
f(8) = 3·8 -2 = 22
f(-5) = 3·(-5) -2 = -17
f(8) - f(-5) = 22 - (-17) = 22 +17 = 39

22. The first part is similar to 21—evaluate the function for x=2.
f(2) = 24 -2·2 = 24 -4
f(2) = 20
Note that this result is sufficient to allow you to choose the correct answer.
However, we can also do the second part. Find x for f(x) = 10
f(x) = 24 -2x
10 = 24 - 2x . . . . . . substitute 10 for f(x)
-14 = -2x . . . . . . . . . subtract 24 from both sides
7 = x . . . . . . . . . . . . . divide both sides by -2

x=41.2
