What is Isosceles Triangle ?An isosceles triangle has two equal sides regardless of the direction the apex (or peak) of the triangle points. Some useful information regarding isosceles triangles is as follows:
It has two parallel sides.It has two equal angles, which are known as the basis angles.A right isosceles triangle is one in which the third angle is 90 degrees.We have a Triangle.
Then, using Isosceles Triangle Theorem
Angles opposite an isosceles triangle's equal sides are also equal.
According to the isosceles triangle theorem, if two sides of a triangle are congruent, then the angles opposite the congruent sides are likewise congruent.
So, x= 42 degree.

Answer:
3/15 x 12/14 = 36/210 = 6/35
Step-by-step explanation:
3 + 12 = 15
3/15 = black
12/15 = green
the probability Lila selects the black ribbon first is 12/15
Lila has taken one away so the total now decreases by one to 14
There are 3/14 black ribbons now, and hence the probability that Jessica takes one is 3/14.
Then you just multiply the two together:
3/15 x 12/14 = 36/210 = 6/35
So as a result, The simplified answer is 6/35

The binomial probability for getting at least 4 successes is 0.955
What is binomial probability?The probability of exactly x successes on n repeated trials in an experiment which has two possible outcomes is called binomial probability.
Binomial probability formula[tex]P_{x} = nC_{x} p^{x} q^{n-x}[/tex]
Where,
P is the binomial probability
x is the number of times for a specific outcomes within n trials
[tex]nC_{x}[/tex] is the number of combinations
p is the probability of success in a single trial
q is the probability of failure on a single trial
n is the number of trials
Let p denote the probability of getting success in a single trial and q denotes the probability of failure in a single trial.
And let x be a random variable denoting the number of success.
According to the given question.
We have
[tex]p = 0.85[/tex]
⇒[tex]q = 1- 0.85 = 0.15[/tex]
Also,
n = 6
Therefore,
The binomial probability of getting at least 4 success
[tex]=P(x\geq 4)[/tex]
[tex]=P(x=4)+P(x=5)+P(x=6)[/tex]
[tex]= 6C_{4} (0.85)^{4} (0.15)^{2} + 6C_{5} (0.85)^{5} (0.15)^{1}+ 6C_{6} (0.85)^{6} (0.15)^{0}[/tex]
[tex]=\frac{6!}{4!21} (0.522)(0.0225)+\frac{6!}{5!1!} (0.443)(0.15)+\frac{6!}{6!0!} (0.4)[/tex]
[tex]=15(0.011)+6(0.066)+1(0.4)[/tex]
[tex]=0.165+0.396+0.4\\=0.955[/tex]
Hence, the binomial probability for getting at least 4 successes is 0.955

Using the volume formula, we will see that the volume of the sphere is V = 381.51 cm^3
How to get the volume of the sphere?
For a sphere of radius R, the volume is given by the formula:
[tex]V = (\frac{4}{3})*3.14*R^3[/tex]
In this case, we can see that the diameter is 9 cm, then the radius is half of that:
R = 9cm/2 = 4.5cm
Now that we know the radius, we can replace it on the volume formula to get:
[tex]V = (\frac{4}{3})*3.14*(4.5cm)^3 = 381.51 cm^3[/tex]

Now you work backwards from 4:00pm.
You go back 2 hours & you would be at 2:00pm

The length of a rectangle is twice its width. The perimiter of the rectangle is 36 ft what are the length and the width of the rectangle?
Answers
Answer:
W = 6', L = 12'
Step-by-step explanation:
Let W be the width and L the length.
We are told that L = 2W
The perimeter is 2L + 2W = 36'
Use the first equation in the second: 2(2W) + 2W = 36'
4W + 2W = 36'
6W = 36'
W = 6'
and since L = 2W, L = 12'
Check: Does a width of 6' and length of 12' make a perimeter of 36'?
2*6' + 2*12' = 36' ?
12'+24' = 36'
YES
The length is 12' and the width is 6'. The lenght is twice the width, and the perimeter adds to 36'.

Charlie will be gone in 6 months, while Dash has 3 more months after til she leaves.
Answer: 18 months
Step-by-step explanation:
If both of them aren't at home, then they hire someone to look after the dog. However, if Charlie is on a trip and Dasha isn't, they don't. So they would need to be at business trips at the same time and that means they will hire someone to look after the dog. So we find the LCM of 6 and 9 which is 18 months.
