What is the value of the contangent of
Given:
In triangle WXY, [tex]m\angle W=90^\circ, WX=8, XY=17, WY=15[/tex].
To find:
The Cotangent of [tex]\angle X[/tex].
Solution:
In a right angle triangle,
[tex]\cot \theta=\dfrac{Base}{Perpendicular}[/tex]
It can be written as:
[tex]\cot \theta=\dfrac{Adjacent}{Opposite}[/tex]
For triangle WXY,
[tex]\cot (\angle X)=\dfrac{WX}{WY}[/tex]
[tex]\cot (\angle X)=\dfrac{8}{15}[/tex]
Therefore, the Cotangent of [tex]\angle X[/tex] is [tex]\dfrac{8}{15}[/tex].

Answer and I will give you brainiliest
Answer:
B) 1594323Step-by-step explanation:
Given GP -9, 27, -81, ...To find12th termSolutionnth term formula
aₙ = a₁rⁿ⁻¹, where r- common ratio, n- number of the termWe have
a₁ = -9r = 27/-9 = -81/27 = -3Find a₁₂
a₁₂ = (-9)*(-3)¹¹ = 1594323Correct choice is B

Could someone help me please?
Answer:
600
Step-by-step explanation:
So lets rememer the formula for volume of a pyramid to sovle this:
LxHxW/3
Now lets plug in our values, for L, H, and W.
15x12x10/3
So, 15x12x10 is 1800. That is the height times the length times the width.
Now, since this isnt volume of a cube, we must divide the total my 3. This is how you find the volume of a pyramid, as I said above.
So it should be:
1800/3
=
600
This is your answer.
I hope this helps : )
Good luck!
A ceramic vase was originally priced at $100 but went on sale for 50% off. If Ernesto bought the ceramic vase and paid 12% sales tax, how much did he pay in total?
Ernesto bought the ceramic vase for $56 including 12% tax.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, A ceramic vase was originally priced at $100 but went on sale for 50% off.
∴ The discounted price is (50/100)×100 = $50.
Now after Ernesto bought the ceramic vase he had to pay a tax of 12%.
∴ {(100 + 12)/100}×50.
= (112/100)×50.
= 56.
So he paid $56 including 12% tax.
