Which set of three angles could represent the interior angles of a triangle?
O 19°, 70°, 91°
O 47°, 12°, 31°
O 50°, 20°, 20°
O 25°, 25°, 100°
Answer:
19 degrees, 70 degrees, and 91 degrees.
Step-by-step explanation:
The interior angles of a triangle sum to 180 degrees. 19 plus 91 is equal to 110, add 70 to 110 and you'll get 180. :)

Using the sine rule, a/sin(A) = b/sin(B) = c/sin(C)
But we have to have at least two angles and two lengths to equate it to one another. We could find the third angle in this triangle to use as our second angle, but we do not know the value of x, so we have to find the second length.
To do that, we use Pythagoras theorem;
a^2 = b^2 + c^2
a^2 = 7^2 + 5^2
a^2 = 49 + 25
a^2 = 74
square root both sides to get rid of the square on a:
a = sqrt(74)
a ~ 8.60
Now we can apply our sine rule. Note that the lengths and angles are the ones opposite each other. For example, the corresponding angle of 8.60 is 90° and the one for 5 is x°.
So,
8.60/sin(90) = 5/sin(x)
8.60/1 = 5/sin(x), since sin(90) = 1
Make sin(x) the subject,
sin(x) = 5/8.60
sin(x) = 0.5814
x = sin^-1(0.5814)
x ~ 35.6°

x2 = 6y
A. (0, 3/2)
B. (0,6)
C. (0, -3/2)
D. (3/2,0)
Answer:
The answer would be (0,3/2) or letter A.
Step-by-step explanation:
In conclusion the answer is letter A (0,3/2)
You welcome.
The co-ordinate of the focus of the given equation of the parabola x^2=6y is (0,3/2).
We have given the equation is
[tex]x^2 = 6y[/tex]
We know that the general equation of the parabola is,
[tex]x^2=4ay[/tex]
A line that passes through the focus and divides the parabola into two halves is known as the axis of symmetry.
What are the coordinates of the focus?
The coordinates of the focus [tex]f(0, a)[/tex]
We have to determine the value of
[tex]a4a=6a \implies 6/4a=3/2[/tex]
Therefore the coordinate of the focus is[tex](0,3/2)[/tex].

Tammy has scored 82, 78, and 93 on her previous three tests. What score does she need on her next test so that her average (mean) is 81?
Answer:
She needs a grade of 71 on her next text.
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is the sum of all values in the data-set divided by the number of values.
Tammy has scored 82, 78, and 93 on her previous three tests.
Thus, her grades are 82, 78, 93 and x, in which x is her grade in the fourth test.
There are 4 tests.
What score does she need on her next test so that her average (mean) is 81?
We have to find x when the mean is 81. So
[tex]\frac{82 + 78 + 93 + x}{4} = 81[/tex]
[tex]253 + x = 324[/tex]
[tex]x = 324 - 253[/tex]
[tex]x = 71[/tex]

Ignacio shares 2.1 liters of water equally into 7 containers. How many milliliters are in each container?
Answer: 300 ml
Step-by-step explanation:
First and foremost, we should note that:
1000 milliliters = 1 liter
Therefore, 2.1 liters = 2.1 × 1000 = 2100 millimeters.
Therefore, since the liters of water is divided into 7 containers, the vlaue in each container will be:
= 2100 millimeters / 7
= 300 millimeters

351.86 square inches. Yes, i know the answer but still clueless how to solve for that. (There was a test and I got the answer wrong then it revealed the right answer)
Will mark brainliest if someone truly helps me.
Answer:
Formula for to find out the surface area of a cylinder = 2πrh+2πr^2
As the radius of the cylinder (4/2) cm = 2cm
Then the surface area of the cylinder
= 2πrh + 2πr^2
=( 2×22/7×2×6 + 2×22/7 × 2^2) cm^2
= (528/7 + 176/7) cm^2
= 704/7 cm^2

Answer:
71°
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
∠H = 180° -109° = 71°
_____
Additional comment
The above rule comes from the more general rule that the measure of an inscribed angle is half the measure of the arc it intercepts. Here, inscribed angle J intercepts arc GHI, so that arc has measure 2×109°. Then the measure of short arc GI is 360° -2×109°, and inscribed angle H is half that:
∠H = (1/2)(360° -2×109°)
∠H = 180° -109° = 71°

How much in interest ?
Answer:
The interest to be charged is $ 3,150.
Step-by-step explanation:
Since Mark is going to purchase a $ 9,000 motorcycle, and his bank will finance his purchase through an add-on interest loan, and they will charge Mark 7% interest over 5 years, to determine how much in interest will be charged, the following calculation has to be done:
9000 x 0.07 x 5 = X
630 x 5 = X
3150 = X
Therefore, the interest to be charged is $ 3,150.
