The values of {x} and {y} in the given right angled triangle is -
x = 9√3 and y = 18.
What is Pythagoras theorem?Pythagoras theorem states that the square of the hypotenuse is equivalent to the square of the base and perpendicular. We can write the formula for Pythagoras theorem as -
(hypotenuse)² = (base)² + (perpendicular)²
Given is a right angled triangle as shown in the image.
We can write the tangent function as -
tan(30) = 9/x
x = 9/tan(30)
x = 9√3
Similarly, we can write the sine function as -
sin(30) = 9/y
1/2 = 9/y
y = 18
Therefore, the values of {x} and {y} in the given right angled triangle is -
x = 9√3 and y = 18.

ROUND TO THE NEAREST TENTH: 50.3
Hope this helps! :)
Answer:
50.2 in.
Step-by-step explanation:
To find the circumference of a circle, multiply the radius by 2, or multiply the diameter by pi.
Here, only the radius is displayed.
8 ⋅ 2 = 16.
16 is the diameter.
Now we can multiply the diameter by pi to get the circumference.
16 ⋅ 3.14 = 50.24
50.24 rounded to the nearest tenth is 50.2
Again, the formula for circumference is diameter ⋅ π (pi).
Therefore, 50.2 in. is the circumference of this circle.

what does b equal b=____
Answers
9514 1404 393
Answer:
b = 90°
Step-by-step explanation:
Angles a, b, c form a linear angle, so their sum is 180°. This means ...
a + b + c = 180°
b = 180° -(a +c)
Angles 'a' and 'c' are complementary, so their sum is 90°.
b = 180° -90°
b = 90°
__
We can also find the measures of the other angles in this geometry.
a = 90° -c = 90° -56° = 34°
e = c = 56° . . . . . . . . . vertical angles
In summary, ...
a = 34°, b = 90°, c = 56°, d = 124°, e = 56°

Vicky is studying French. She spends 1 hour reviewing each old chapter. She also spends 1.5 hours learning each
new chapter. She spends at least 10 hours per week studying French. Which graph could represent the possible
number of old chapters Vicky reviews, x, and new chapters Vicky learns, y, each week?
Answers
The answer is D
Step-by-step explanation:
The graph B is correct.
What is graph?The pictorial representation of data is called the graph.
Given that, Vicky gives 1 hour reviewing each old chapter and 1.5 hours learning each new chapter.
She spends at least 10 hours per week studying French.
We need to find the graph for this relation,
Let the number of old chapters Vicky reviews be x, and new chapters Vicky learns be y,
Therefore,
x + 1.5 y ≥ 10
Put the graph for the same.
Since the inequality sign is '≥' so the shaded part will be above the line and the inequality sign involves both equal and inequality so the line will be solid line without the dash.
We get the second graph is the correct graph.
Hence the graph B is correct.
