Answer:
51°+71°+<C= 180° Sum of interior angle of triangle
C + 122° = 180°
C = 180°- 122°
C = 58°
Answer:
=A=
Find m∠C
m∠C = 180° - (51° + 71°) = 58°Find the missing sides using the law of sines:
9.8 / sin 71° = AB / sin 58° = AC / sin 51°AB = 9.8 sin 58° / sin 71° = 8.8 cmAC = 9.8 sin 51° / sin 71° = 8.1 cm=B=
Find m∠L
m∠L = 180° - (42° + 84°) = 54°Find the missing sides using the law of sines:
50 / sin 84° = KL / sin 42° = JK / sin 54°KL = 50 sin 42 °/ sin 84° = 33.6 cmJK = 50 sin 54° / sin 84° = 40.7 cm=C=
Find m∠R using the law of sines:
17.5 / sin 98° = 15 / sin ∠Rsin ∠R = 15 sin 98° / 17.5sin ∠R = 0.85m∠R = arcsin (0.85) = 58.2°Find the missing angle:
m∠S = 180° - (98° + 58.2°) = 23.8°Find the length of QR, use the law of sines:
17.5 / sin 98° = QR / sin 23.8°QR = 17.5 sin 23.8° /sin 98° = 7.1 m4. Which graph represents the solution to
-2<3x+1 ?
Hey there!
-2<3x+1
= 3x + 1 < -2
SUBTRACT 1 to BOTH SIDES
3x + 1 - 1 < -2 + 1
CANCEL out: 1 - 1 because that gives you 0
KEEP: -2 + 1 because that helps you solve for x
-2 + 1 = -3
New EQUATION: 3x > -3
DIVIDE 3 to BOTH SIDES
3x/3 > -3/3
CANCEL out: 3/3 because that gives you 1
KEE3 -3/3 because that helps us compare for x
-3/3 = -1
Answer to the equation: x > -1
OVERALL Answer: x > -1; It is an OPENED circle shaded to the right starting at -1 (Option A.)

The sizes of cans on a shelf are listed below.
18 oz, 8 oz, 16 oz, 20 oz, 20 oz, 16 oz, 12 oz, 8 oz
What is the interquartile range of this list?
2
6
9
12
Answer:
9
Step-by-step explanation:
The interquartile range of the given list is 11 oz.
What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
To find the interquartile range (IQR), we first need to find the first quartile (Q1) and the third quartile (Q3) of the data.
To do this, we first need to order the data set from smallest to largest:
8 oz, 8 oz, 12 oz, 16 oz, 16 oz, 18 oz, 20 oz, 20 oz
Next, we find the median of the data set. Since there are 8 data points, the median is the average of the two middle values:
Median = (16 oz + 16 oz)/2 = 16 oz
Now we can find Q1 and Q3. Q1 is the median of the lower half of the data set, and Q3 is the median of the upper half of the data set.
Lower half: 8 oz, 8 oz, 12 oz, 16 oz
Upper half: 16 oz, 18 oz, 20 oz, 20 oz
Q1 = (8 oz + 8 oz)/2 = 8 oz
Q3 = (18 oz + 20 oz)/2 = 19 oz
Finally, we can calculate the IQR as the difference between Q3 and Q1:
IQR = Q3 - Q1 = 19 oz - 8 oz = 11 oz
Therefore,
The interquartile range of the given list is 11 oz.

Some for all values of x by factoring
Answer:
{-1, 10}
Step-by-step explanation:
Next time please share the entire set of instrutions.
x^2 - 9x - 15 = -5 should be rewritten in standard quadratic form:
x^2 - 9x - 10 = 0 = (x - 10)(x + 1) = 0.
Setting each factor equal to zero and then solving for x yields {-1, 10}

The lengths of the legs of a right triangle are 6 cm and 8 cm What is the length of the hypotenuse?
Answer:
The hypotenuse is 10 cm long.
Step-by-step explanation:
We can find the hypotenuse by using the following formula where "c" is the length of the hypotenuse and "a" and "b" are the lengths of the legs.
[tex]c = \sqrt{a^{2} + b^{2} }[/tex]
Now we just substitute the values and get...
[tex]c = \sqrt{a^{2} + b^{2} }\\c = \sqrt{6^{2} + 8^{2} } \\c = \sqrt{36 + 64} \\c = \sqrt{100} \\c = 10[/tex]
Therefore the hypotenuse is 10 cm long.
