Answer:
54.5°
Step-by-step explanation:
You know that in a right triangle, the sine of an angle is given by ...
Sin = Opposite/Hypotenuse
sin(D) = EF/ED = 57/70
The inverse sine function is used to find the angle:
∠D = arcsin(57/70)
∠D ≈ 54.5°
Answer:
A.
Step-by-step explanation:
A. City voters were asked about candidates. That seems to be random.
B. A survey about singers took place at a specific concert. Naturally, the people who are there like this singer. It is not random.
C. Customers were asked about food at a pizza shop. Naturally, they like pizza. This is not random.

Answer: A.
Answer:
x=118.25
Step-by-step explanation:
3−2x=−1.5−6−226
3+−2x=−1.5+−6+−226
−2x+3=(−1.5+−6+−226)(Combine Like Terms)
−2x+3=−233.5
−2x+3=−233.5
Step 2: Subtract 3 from both sides.
−2x+3−3=−233.5−3
−2x=−236.5
Step 3: Divide both sides by -2.
−2x
−2
=
−236.5
−2
x=118.25
Answer:
Okay so what you are looking at is a triangle with a cross section. That is line segment PQ.You ae asked to find the length of PN. What you are given is the height(s) of NQ (5 units), QM (2 units) and PL (3 units). You can make an educated guess that line NP equals 4 units. Mainly because those two little arrows on lines LM and PQ (that means that the two lines are parallel). hope it helps...
X is 9
12x + 17 = -1 + 14x
18 = 2x
x = 9
