Answer:
66
Step-by-step explanation:
Find the last side of the triangle using the Pythagorean theorem.
[tex]c^{2} = a^{2} + b^{2} \\20^{2} = 8^{2} + b^{2}[/tex]
B=[tex]4\sqrt{21}[/tex]
This makes b = 18.3
Now you can find the angle B = arcsin (opp/hyp)
B=arcsin [tex]\frac{4\sqrt{21} }{20}[/tex]
B= 66.42
Answer:
22°
Step-by-step explanation:
Okay, to first find the missing side, you need to use a² +b² = c²
getting 21.54 for the hypotenuse. From there, you're going to divide the leg (8) that's opposite of the angle you're trying to find and divide it by the hypotenuse (21.54). Then on you're caluclator you should have a button that says "Sin-1". You're going to use that and plug in the answer you got from 8/21.54. This'll give you your answer!

The value of x according to the given information is 8
Sum of interior angleThe sum of interior angle of a triangle is equal to the exterior
Given the following
interior angles = PQR=(2x+6) and ∠RPQ=(x−7)
exterior = m∠QRS=(5x−17)
According to the theorem
5x -17 = 2x+6+ x - 7
5x - 17 = 3x - 1
5x-3x = -1 + 17
2x = 16
x =8
Hence the value of x according to the given information is 8

What is the distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3?
Answer:
The distance is [tex]\sqrt{20}[/tex] or [tex]2\sqrt{5}[/tex].
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula [tex]\sqrt{(x_{2}-x_{1} )^{2}+(y_{2} -y_{1})^2 }[/tex]
Insert (0,7) and (4,5)
[tex]\sqrt{(0-4)^{2}+(7-5)^2 }[/tex] = [tex]\sqrt{(-4)^{2}+(2)^2 } = \sqrt{(16)+(4)} } = \sqrt{20} = 2\sqrt{5}[/tex]
The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex] and can be determined by using the point-slope form and also by using the distance formula.
Given :
y = 2x + 7y = 2x - 3First, determine the line perpendicular to the line (y = 2x + 7) whosw slope is -1/2 and intersect the line (y = 2x + 7) at point (0,7).
Using the point-slope, the equation of the perpendicular line can be determined.
[tex](y-y_1)=m(x-x_1)[/tex] ---- (1)
where m is the slope and [tex](x_1,y_1)[/tex] is the point on the line.
Now, put the value of known terms in the equation (1).
[tex]y-7=-\dfrac{1}{2}(x-0)[/tex]
y = -0.5x + 7 --- (2)
Now, determine the point of intersection between lines (y = -0.5x + 7) and (y = 2x -3).
Substitute the value of y that is (y = 2x - 3) in equation (y = -0.5x + 7).
2x - 3 = -0.5x + 7
2.5x = 10
x = 4
Now, put the value of x in the equation (y = -0.5x + 7).
y = -0.5(4) + 7
y = 5
Now, the distance between two points is given by the equation:
[tex]\rm D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm D = \sqrt{(0-4)^2+(7-5)^2}[/tex]
[tex]\rm D = \sqrt{20}[/tex]
[tex]\rm D = 2\sqrt{5}[/tex]
The distance between parallel lines whose equations are y = 2x + 7 and y = 2x – 3 is [tex]2\sqrt{5}[/tex].

Would any three squares

triangle? Explain.
Three squares of sides 15 units, 9 units, and 12 units can form a
right-angled triangle.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
Given, We have to form a right-angled triangle that has side lengths of
3 different squares.
Let, The first square has a side length of 9 units, and let this be the height of the right-angled triangle.
Another square has a side length of 15 units and this is the hypotenuse.
Therefore, the base of the triangle must be 15² - 9² = 225 - 81 = 144 = 12 units.
So, The third square must have a side length of 12 units.

Answer:
x = 289 degrees
Step-by-step explanation:
The sum of angle measures in a hexagon is 720 degrees. One can apply this information here, by forming an equation. Add up all of the angle measures, including parameter (x), simplify and use inverse operations to solve for the numerical value of the parameter (x).
100 + 102 + 108 + 121 + x = 720
Simplify,
431 + x = 720
Inverse operations,
431 + x = 720

If the area of a square is 7.29 square yards, what is the length of one of the sides?
Answer:
2.7
Step-by-step explanation:
Since the shape is a square, just square root its area to get its side's sides.
Square root 7.29:
2^2 is 4, and 3^2 is 9, so we know that the answer is somewhere between 2 and 3
Let's try 2.5:
2.5^2 = 2.5*2.5 = 6.25, not quite
Let's try 2.6:
2.6^2 = 2.6*2.6 = 6.76, still a bit short
Let's try 2.7:
2.7^2 = 2.7*2.7 = 7.29, We have 7.29, so 2.7 is the answer!
