Answer:
Step-by-step explanation:
In Δ AFB,
∠AFB + ∠ABF + ∠A = 180 {Angle sum property of triangle}
90 + 48 + ∠1 = 180
138 + ∠1 = 180
∠1 = 180 - 138
∠1 = 42°
FC // ED and FD is transversal
So, ∠CFD ≅∠EDF {Alternate interior angles are congruent}
∠2 = 39°
In ΔFCD,
∠2 + ∠3 + ∠FCD = 180
39 + ∠3 + 90 = 180
129 +∠3 = 180
∠3 = 180- 129
∠3 = 51°
Answer:
B.-38
Step-by-step explanation:
2x - 18 = y ...(1)
x = -10 (Given)
Now,
Put the value of x in equation (1) we get,
2(-10) - 18 = y
-20 - 18 = y
-38 = y
<em><u>y = -38</u></em>
Thus, the value of y is -38
Answer:
Your answer is 0 (zero).
<u>Step</u><u> </u><u>by</u><u> </u><u>Step</u><u> </u><u>Explanations</u><u>:</u>
<u>For</u><u> </u><u>mean</u><u>:</u>
1. Add all the numbers; which is 90
2. Divide by how numbers there are, for this case there are 6 numbers; 90/6 = 15
3. Your mean is 15
For Median:
1. Order the numbers from lest to greatest. Ex: 8, 10, 12, 18, 20, 22
2. Find the middle number(s), which are 12 &18
3. Add; 12 + 18 = 30
4. Divide; 30/2 =15
5. Your Median is 15
So now the question asks "what's the difference?" which means subtraction: 15 - 15 = 0
Answer: 9
<u>Step-by-step explanation:</u>
Andre has 4 x (the number of cars Peter has). Andre has 36 cars.
4P = 36
P = 9
Answer:
A collection of short stories.
Step-by-step explanation:
A classic novel is almost always fiction, which is not suitable for referencing. A commercial website publicly advertises its products or services. Again, not professionally referenceable. This leaves us with a collection of short stories. This option is correct because the stories come from realistic and personal accounts.
