How do I know which triangles are similar to ABC?
Answer:
I'm not sure if my answer is correct but anyways.
Step-by-step explanation:
If you drew a triangle and labeled it, that would be easier to determine your answer. So, 145-10=135 and then i guess 145-135=10???

a) In the given figure, ABC – XCY, BC = 9 cm,
BY = 3 cm and XY = 4 cm.
Find the length of AB.
Answer:
AB = 12 cm
Step-by-step explanation:
AB/BC = XY/BY
From the above question:
AB = ??
BC = 9cm
XY = 4cm
BY = 3 cm
AB/9 = 4/3
Cross Multiply
AB × 3 = 9 × 4
AB = 9 × 4/3
AB = 12 cm
Therefore, Length AB = 12cm

Answer:
We conclude that:
[tex]\left(\:\:\frac{x^4}{\frac{3x^2}{3}}\right)^{\frac{1}{3}}\:=\:x^{\frac{2}{3}}[/tex]
Hence, option A i.e. [tex]x^{\frac{2}{3}}[/tex] is true.
Step-by-step explanation:
Given the expression
[tex]\left(\:\:\frac{x^4}{\frac{3x^2}{3}}\right)^{\frac{1}{3}}[/tex]
Apply exponent rule: [tex]\left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}[/tex]
[tex]\left(\frac{x^4}{\frac{3x^2}{3}}\right)^{\frac{1}{3}}=\frac{\left(x^4\right)^{\frac{1}{3}}}{\left(\frac{3x^2}{3}\right)^{\frac{1}{3}}}[/tex]
[tex]=\frac{x^{\frac{4}{3}}}{\left(\frac{3x^2}{3}\right)^{\frac{1}{3}}}[/tex] ∵ [tex]\:\:\:\left(x^4\right)^{\frac{1}{3}}=x^{\frac{4}{3}}[/tex]
[tex]=\frac{x^{\frac{4}{3}}}{\frac{\left(3x^2\right)^{\frac{1}{3}}}{3^{\frac{1}{3}}}}[/tex]
[tex]=\frac{x^{\frac{4}{3}}}{x^{\frac{2}{3}}}[/tex]
Apply exponent rule: [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]
[tex]=x^{\frac{4}{3}-\frac{2}{3}}[/tex]
[tex]=x^{\frac{2}{3}}\\[/tex]
Therefore, we conclude that:
[tex]\left(\:\:\frac{x^4}{\frac{3x^2}{3}}\right)^{\frac{1}{3}}\:=\:x^{\frac{2}{3}}[/tex]
Hence, option A i.e. [tex]x^{\frac{2}{3}}[/tex] is true.

Answer:
-4
Step-by-step explanation:
Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.
So to solve for x, set 28 and 10x+68 equal to each other.
28=10x+68
First, subtract 68 from both sides
-40=10x
Then, divide both sides by 10
-4=x
If you want to check your answer plug -4 back into the original equation.
28=10(-4)+68
28=-40+68
28=28, which is true, therefore -4 is correct.
There are two mystery numbers. The sum of 2 times the first number and 3 times the second number is -18. The sum of 3 times the first number and 2 times the second number is -17. What are the two numbers?
Answer:
-3 and -4
Step-by-step explanation:
x = 1st number
y = 2nd number
set up system of equations:
2x + 3y = -18
3x + 2y = -17
elimination method: multiply 1st equation by -2 and second by 3
-4x - 6y = 36
+
9x + 6y = -51
5x = -15
x = -3
find y: 2(-3) + 3y = -18
-6 + 3y = -18
3y = -12
y = -4

Answer:
5. 28.39
6. 58.18
Step-by-step explanation:
5. To find x, use tangent since you know the opposite and adjacent legs
tangent is opposite/adjacent
tan(x)=20/37
x=tan-1(20/37)
x=28.39
6. you want to find the hypotonuse of XYZ to use tangent to find angle W
Sin(25)=15/x
0.423=15/x
0.423x=15
x=35.46
this is the hypotonuse
now use tangent to find W
tan(x)= 35.46/22
x=tan-1(35.46/22)
x=58.18
Solve the equation.

Find the coordinates for points are that proves figure trap is an isosceles trapezoid?
Answer:
Coordinates of point R → (c - a, b)
Step-by-step explanation:
From the picture attached,
By the property of an isosceles trapezoid,
PX = AY = a
Therefore, horizontal distance of Y from the origin PY = AP - AY
PY = c - a
Vertical distance of point R from x-axis (RY) = b
Therefore, coordinates of point R will be (c - a, b).

Bus X, Bus Y and Bus Z leave the bus terminal every 35 minutes, 40 minutes and 42 minutes respectively. Given that the 3 buses leave the interchange together at 0620, what would be the next time the three buses leave together?
Answer:
Step-by-step explanation:
Find the lowest common multiple between the numbers
35 = 5×7
40 = 2³×5
42 = 2×3×7
So the lowest common multiple is:
2³×3×5×7 =840 minutes
840 minutes is 14 hours so the next time they are all at the interchange is 2020 hours.

In an inverse variation, X = -8 when
y= - 1/4. What is the value of y when x = 4?
Step-by-step explanation:
xy = k, where k is a real constant.
When y = -1/4, x = -8.
=> k = (-8)(-1/4) = 2.
Therefore when x = 4,
y = k/x = (2)/(4) = 0.5.
In an inverse variation the value of y is 0.5
What is the value of y ?
In an inverse variation, X = -8 wheny= - 1/4.
y= - 1/4.
the value of y when x = 4
In the equation xy = k, k is a real constant.
X equals -8 at y = 1/4.
=> k = (-8)(-1/4) = 2.
Consequently, if x = 4,
y = k/x = (2)/(4) = 0.5.
In an inverse variation the value of y is 0.5.
Solving an Inverse Variation Problem:
The variation formula is either y = k/x or k = xy.Replace with the supplied values to determine the value of k.With the known value for k, rewrite the variation equation as y = k/x.Find the unidentified by substituting the remaining values.To learn more about inverse variation refer to:
