Using row 4:
<span>coefficients are: 1, 4, 6, 4, 1 </span>
<span>a^4 + a^3b + a^2b^2 + ab^3 + b^4 </span>
<span>Now adding the coefficients: </span>
<span>1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + 1b^4 </span>
<span>Substitute a and b: </span>
<span>a = 4x </span>
<span>
b = -3y </span>
<span>1(4x)^4 + 4(4x)^3(-3y) + 6(4x)^2(-3y)^2 + 4(4x)(-3y)^3 + 1(-3y)^4 </span>
<span>Now simplify the above: </span>
<span>256x^4 - 768x^3y + 864x^2y^2 - 432xy^3 + 81y^4 </span>
Answer:
x = 45
y = 45
z = 11.1
Step-by-step explanation:
Remark
The triangle is a right triangle. That means that it has 1 right angle.
It is also isosceles which means that the two legs that are not the hypotenuse are equal.
Result: z and 11.1 are equal z = 11.1
More remark
If the triangle is isosceles, that means that the angles that are not right angles must also be equal.
90 + x + y = 180
but x = y
90 + 2x = 180 Subtract 90
2x = 180 - 90 Divide by 2
2x/2 = 90/2
x = 45
Answer:
a= 20 b= 160 c= 90
Step-by-step explanation:
Based on how 20 is the angle as you can see by the arrow I made the assumption that a is 20 degrees and for c my estimated guess is 90 because if you imagine how many of the 20 degree angle can fit there you get around 80-90 so I made the guess it was option C. I am sorry if this doesn't make sense I tired to understand it I hope you get the answer right. Also enjoy the rest of your day!
Hello,
c1=10.9 (in) A1=392.4 (in²)
c2=21.8 (cm) =21.8/2.54 (in)
k=c2/c1=(21.8/(2.54*10.9)=2/2.54
A2=(2/2.54)²*392.4=243,28848...≈243.29 (in²)
